This invention generally relates to computer systems. More particularly, this invention relates to a method and system for configuring an electronic device.
Many electronic devices are configurable. Such configuration typically requires entering data into the electronic device to be configured in order to program the device to operate in a particular way. Unfortunately, the user interface (UI) on many electronic devices is limited. For example, the UI of the device may only include controls designed to facilitate its use, e.g. tuning a radio to a desired frequency, but that are not optimized for more complex data entry, which may be necessary as part of the device's initial configuration or to later change the device's operating parameters. As a result, using the device's UI to perform its configuration is often complex, counterintuitive, and prone to errors. Other electronic devices lack any UI at all or have such a limited UI, e.g. only an on/off button, such that configuration of the device via its UI impractical.
Even computers and other electronic devices having a more sophisticated UI are difficult to configure for some applications. For example, some home networks use wireless technology, such as 802.11 and Bluetooth-enabled technology. Wireless technology provides a desirable way to implement home networks because of its convenience, mobility, and flexibility. However, configuring devices to communicate over a home network usually requires manual entry of setup information at a network component, such as a wireless access point. This process is difficult for some users, particularly in the case of home networks where the user may lack experience in setting up networks. If the network uses a security protocol, setting up the network becomes even more difficult. The problems associated with setting up a network can be further compounded when data necessary to setup the network or to add a new network device needs to entered at a device that lacks a sophisticated UI.
From the foregoing, it is apparent that an improved method and system is needed to more efficiently allow electronic devices, computers, and peripherals to be configured and, if desired, integrated within a networking environment.
The invention is directed to a method and system for automatically configuring an electronic device without the need for complex data entry by a user. In accordance with the method of the present invention, configuring the electronic device includes using a host computer and a portable storage device. The portable storage device has an interface that is compatible with both the host and the new device. The portable storage device is first interfaced to the host and the host determines whether the portable storage device includes device specific data that uniquely identifies the electronic device. Based on the device specific data, or the lack of such device specific data, the host selects a configuration file having configuration data for the electronic device. A copy of the configuration file is then stored on the portable storage device. The portable storage device is then interfaced to the electronic device and the configuration data stored thereon is used to configure the electronic device.
In accordance with an embodiment of the present invention, the configuration data includes network configuration data that permits the electronic device to communicate over a network. Communication over the network is optionally conducted according to a security protocol.
Another embodiment of the invention is directed to a portable storage device or other device serving a similar purpose. The portable storage device is a multi-connector portable storage fob adapted to store configuration data for an electronic device and to provide an interface between a host computer and the electronic device. The storage fob includes a processor for executing program instructions and a memory for storing the configuration data. The storage fob also includes a plurality of interfaces including a first connector and a second connector. The first connector is adapted to interface to the host and the second connector is adapted to interface to the electronic device. The storage fob further includes a switch that prevents simultaneous electrical connection of the first and second connectors.
In yet another embodiment, the invention is directed to a method of configuring network components such as a network access point or client device. The network component is directly connected to the system bus of the host computer. Following a plug and play enumeration step, the host queries the network component for its network capabilities. The network component responds to the host with its wireless capabilities and the host creates a resultant profile defining a set of configuration settings. The configuration settings include wireless parameters to be used by the network component when communicating over the network. The host thereafter sends the set of configuration settings to the network device, which device is configured according to the configuration settings. The network component is then capable of communicating over the network.

As generally shown, the environment 200 includes a host 202 and a new device 204. The host 202 is any suitable computing device such as the computing device described with reference to
The host 202 includes an interface 206. Through the interface 206, the host 202 is communicatively coupled to external devices, such as the PSD 218. In one embodiment, the interface 206 provides a physical connection to an external device. Examples of suitable types of interfaces that provide the physical connection include serial port, parallel port, PCI port, or any type of USB port. Alternatively, the interface 206 provides a wireless connection to external devices. Examples of suitable interfaces that provide the wireless connection include an infrared transmitter/receiver or RF circuit capable of reading from and writing to an RF Id tag type device. The interface 206 is integral to the host 202 or alternatively is a separate device connected to, and in communication with, the host. Of course, it will be understood that the host 202 may include a plurality of interfaces and each of the plurality of interfaces may be of a different type.
The new device 204 is any electronic device capable of being configured, i.e. programmed with data that represents user preferences or that provides instructions on tasks to be performed. The new device 204 includes electronic components and circuitry that facilitate its configuration. Examples of such electronic components include a microprocessor or microcontroller and temporary or permanent storage, such as RAM, EEPROM or flash memory. By way of example and not limitation, types of new devices 204 include media players, cameras, watches, cell phones, personal digital assistants (PDAs), remote controls, IP speakers, consumer electronics, A/V equipment, TVs, satellite receivers, printers, faxes, computers, routers, wireless access points, and bridges.
The new device 204 also includes an interface 208 that permits the new device to interface to external devices. The interface 208 of the new device 204 provides a physical or wireless connection to an external device, examples of which include serial port, parallel port, USB port, infrared transmitter/receiver, or a writeable RF tag. The type of connection provided by the interface 208 of the new device 204 need not be the same type of connection provided by the interface 206 of the host 202.
The operating environment 200 optionally includes a network 210. The network 210 includes the host 202 and other network devices, such as network nodes 212, 214. The network nodes 212, 214 are any suitable electronic device having a network interface. Although not shown, one or more of the host 202, the network nodes 212, 211, and the new device 204 are further optionally connected to an external network such as the Internet.
The network 210 is implemented in any suitable manner. Examples of suitable networks include Ethernet, 802.11 wireless, Wi-Fi, Home Phone Line Network (HomePNA) and the like. The network may include other components necessary for wireless communication, such as wireless access point (WAP) 220 needed for some types of networks, such as 802.11 compliant networks. The WAP 220 may be integral to the host 202 or, alternatively, may be a separate device communicatively coupled to the host 202.
The network 210 optionally employs a security protocol to protect the data exchanged over the network. Examples of known network security protocols include Wireless Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), and Internet Protocol Security (IPSec). It will be understood that the forgoing types of networks and security protocols are only provided by way of example, and not limitation, as the present invention is capable of being implemented with any suitable type of network and security protocol.
According to the method and system of the present invention, the host 202 configures the new device 204 by creating a configuration file 216 (also referred to herein as a profile), or other representation or locator for desired device settings, and transferring a copy of the configuration file 216 to the new device 204 using a personal storage device (PSD) 218. The method of creating and transferring a copy of the configuration file 216 using the PSD 218 is further described with reference to
In one embodiment of the present invention, the PSD 218 is an external device capable of communicating with the host 202 and the new device 208 via their physical or wireless interfaces. A specific example of an external PSD is a multi-connector storage fob described with reference to
In another embodiment of the present invention, the PSD 218 is integral, i.e. a component part of, the new device 204. For example, the PSD 218 is an RF Id tag integral with the new device 204. RF Id tags are known devices that can be read from, or written to, when brought into proximity of an RF read/write device.
The data in the configuration file 216 includes one or both of device specific data and configuration data. Alternatively, the configuration file includes a representation or locator for the device specific data or configuration data. The configuration data is data used to configure the new device 204. In the example shown, the configuration data includes a network identifier, security information and known services. The network identifier is data that identifies the particular network to which the new device is added. Examples of such network identifiers include a security set identifier (SSID), which provides a numeric identification of a network, a computer name, a domain name and/or a workgroup name.
The security information is data needed to communicate over the network using a security protocol. Such information includes, by way of example, identification of a security protocol and a secret, e.g. a cryptographic key, to be shared by the new device and other network devices. Examples of security protocols include WEP, WPA, and IPSec to name a few. The key is used for authentication and implementation of the security protocol and may be used derive additional cryptographic keys. Because the user is not required to manually enter the key, a large key value, i.e. key value of many bits, can be used without increasing the complexity of the configuration process. Accordingly, the present invention facilitates a more secure environment as larger key values generally correspond to cryptographic algorithms that are more difficult to compromise.
The known services data identifies a location on the network where the new device obtains additional configuration data or other information that is useable by the new device. For example, the directory of known services may include identification of a particular directory on the host such as “Music=\shared music” that includes audio files. If the new device has the ability play audio files, such known services data provides the new device with the location on the network where the audio files are accessible. If the network 210 is coupled to an external network, such as the Internet, the known services may include a universal resource locator (URL) address that is accessible by the new device, e.g. “www.foo.com.” The known services data may also be a location and name of a particular application useable by the new device. The new device can then load the application into its memory or use the application via the host.
It will be understood that the foregoing descriptions of types of the configuration data are exemplary. The exact configuration data included in the configuration file 216 depends upon the type of new device 204 to be configured and its capabilities. For example, if the device is not capable of communicating over a network, or if a network is not used, network settings, such as network identification and security setting are not used. Examples of other types of configuration data include data representing the time and date or data that represents a user's favorite radio or TV channels. If the new device is a computer or PDA, the configuration data can include common setup data that user wants to transfer to the device. For example, the common setup data includes data that identifies favorite web sites or user preferences such as a default printer to name a few.
The device specific data is used for at least two purposes in accordance with the present invention. First, the device specific data is useable by the host 202 to determine the type of new device 204, which allows the host to construct a configuration file appropriate 216 for the new device 204. Second, the device specific data is useable by the host 202 to add the new device 204 to the network 210.
The device specific data includes data that uniquely identifies the new device 204. An example of device specific data is identification of the manufacturer name, make and model of the new device 204, e.g. “ABC Corp. Radio Model 123.” Alternatively, or in conjunction with the foregoing example, the device specific data includes an identification number that is unique to the device such as a serial number, RF Id, or media access control (MAC) address.
Turning to
As shown in step 302, the host 202 interfaces to the PSD 218. As previously described herein, the host 202 includes interface 206 that provides a physical connection to the PSD 218. The PSD 218 includes a suitable reciprocal interface. For example, if the interface 206 of the host 202 is a USB port, the PSD 218 includes a compatible USB connector. Alternatively, the host 202 includes interface 206 that provides a wireless connection to the PSD 218 and the PSD 218 includes a reciprocal wireless interface. For example, the host includes an RF Id tag read/write device and the PSD 218 includes an RF Id tag.
In step 304, the host 202 determines whether the PSD 218 includes a configuration file 216 stored thereon. If the PSD 218 includes a configuration file 216, the PSD 218 determines whether the configuration file 216 includes device specific data corresponding to the new device. The device specific data is stored on the PSD 218 if the PSD was previously interfaced with the new device 204 or if the PSD 218 is integral to the new device 204. As previously described, the device specific data uniquely identifies the new device, examples of which include a device type, manufacturer name, model number, serial number, RF Id, MAC address or combination thereof.
If the PSD 218 does not include device specific data, the host transfers a copy of the configuration file 216 to the storage device as shown in step 312. In this case, the configuration data is default configuration data. An example of default configuration data is data needed for the new device to communicate over the network, e.g. network identification, security information, and the like. Alternatively, if the PSD 218 does not include device specific data, the host elects not to attempt to configure the new device 204 in which case the process ends. If this occurs, the PSD 218 can be interfaced to the new device 204 to obtain a configuration file 216 having device specific data as described with reference to
Returning to step 304, if the PSD 218 includes device specific data, the host 202 attempts to use the device specific data to identify configuration data specific to the new device as shown in step 306. For example, the host 202 may have a stored configuration file 216 for the same device, which may occur, for example, if the new device 204 was previously configured but needs to be reprogrammed. As another example, the host 202 may have created a previous configuration file for a device of the same type, e.g. radio, and certain configuration data from the previous configuration file is suitable configuration data specific to the new device, e.g. data that represents the user's favorite channels. As yet another example, the host 202 may communicate with other network devices to obtain suitable configuration data specific to the new device. Alternatively, or in combination with the foregoing, the host 202 uses the device specific data to search for configuration data specific to the new device on an external network, such as the Internet. For example, the host searches the website of the manufacturer to find configuration data specific to the new device. Thus, if the device is of a type Widget manufactured by ABC Inc., the host accesses the internet and attempts to access the website ABC.com. If the site exists, the host then searches for configuration data for “Widget.”
After the host 202 identifies the configuration data specific to the new device 204, the host modifies the default configuration file to include the configuration data specific to the device as shown in step 310. The host 202 then transfers the configuration file 216 to the PSD 218 as sown in step 312. After the process 300 is complete, the PSD 218 is disconnected from the host 202.
In an alternative embodiment, if the PSD 218 includes device specific data, as determined in step 304, the host 202 attempts to communicate with the new device 204 over the network 210 using, for example an RF Id, MAC address or other suitable device specific data. If the host 202 is able to communicate with the new device 204, the new device is added to the network 210 and, optionally, the new device 204 is configured by the 202 host via the network connection.
a and
The PSD 218 is first interfaced to the new device 204 as shown in step 402. By way of example, if the PSD 218 and the new device 204 each provide a physical interface, such as USB port/connectors, the USB connector on the PSD 218 is inserted into the appropriate interface 208 on the new device 204. If the PSD 218 and new device 204 each provide a wireless interface, e.g. an infrared transmitter/receiver, step 402 is executed by bringing the PSD 218 within range of the new device, i.e. such that the PSD 218 and new device 204 can communicate via the wireless connection. Optionally, if step 402 is being carried out for the first time, i.e. the PSD 218 has not previously been interfaced to the new device 204, a driver program is automatically transferred from the PSD 218 to the new device 204 to permit communication therebetween. Automatically downloading the driver is appropriate if the new device 204 is not capable recognizing the PSD 218 without the driver, as is the case with some older software programs and USB compliant storage devices. Such driver programs and methods for downloading drivers are known and need not be described in more detail herein.
In step 404, the PSD 218 determines whether the new device is an active device or a passive device. An active device is a new device 218 that attempts to read the configuration file 216 from the PSD 218 following execution of step 402 within a predetermined period of time. A passive device exhibits the opposite behavior, i.e. does not attempt to read from the PSD 218 following execution of step 402. Thus, if the new device 204 attempts to read from the PSD 218 within the set period of time, it is determined to be an active device. If the new device 204 fails to attempt to read from the PSD 218 within the set period of time, it is determined to be a passive device.
If the new device 204 is active, the new device 204 controls and reads the configuration file from the PSD 218 as shown in step 406. Otherwise, as shown in step 408, the PSD 218 device controls the remaining process 400.
In step 410, a determination is made as to whether at least one useable configuration file exists on the PSD 218. A useable configuration file includes configuration data recognized by the new device 204. For example, if the new device includes a network interface, configuration file 216 having configuration data with network parameters, such as network identification and security data, is a useable configuration file. If the new device 204 is a radio tuner, configuration file 218 having configuration data that identifies preset channels or a location where preset channels are stored on the network, forms a useable configuration file. On the other hand, if the new device 204 does not include a network interface and the configuration file 218 is limited to network configuration data, the configuration file is not a useable configuration file for the new device 204.
If a useable configuration file does not exist, the method 400 proceeds to step 412 and a determination is made as to whether the new device 204 includes any device specific data. As described previously herein, device specific data includes, for example, a manufacturer name and model number of the new device. Alternatively, or in combination with the foregoing, the device specific data includes an identification code, such as an RF Id code. If device specific data exists, the device specific data is transferred to the PSD 218 as shown in step 416. The device specific data is then useable by the host to attempt to create the useable configuration file by, for example, carrying out the method described with reference to
Returning to step 410, if at least one useable configuration file exists, the method 400 proceeds to step 414 where a determination is made as to whether multiple useable configuration files exist. For example, the PSD 218 may include a plurality of configuration files with network configuration data wherein each file represents a different level of network privileges, e.g. a first configuration file for system administrators, a second configuration file for users, and a third configuration file for guests.
If multiple useable configuration files exist, the method 400 proceeds to step 420 where one of the configuration files is selected. Any suitable process is used to select the configuration file. For example, the most recent useable configuration file is selected. Alternatively, the PSD 218 may include a switch and the position of the switch determines which configuration file is selected. For example, if the plurality of useable configuration files each include configuration data for different levels of network privileges, the switch is used to determine which privilege level, e.g. administrator, user, or guest is appropriate and to be selected for the new device. The configuration file 216 having the configuration data that matches the privilege level represented by the switch position is the selected useable configuration file.
After one of the useable configuration files is selected, a copy of the selected configuration file is loaded onto the new device 204 as shown in step 422. Returning to step 414, if only a single useable configuration file exists, a copy of the single useable configuration file is loaded onto the new device as shown in step 422 without the need to select among multiple configuration files. The configuration file 218 is then stored in the temporary or permanent memory or both of the new device 204.
If the new device 204 is not capable of communicating over the network, i.e. does not have a network interface, or if the configuration file does not include network configuration data, the process ends as shown at step 424.
If the new device 204 is network capable, it examines the configuration file to determine whether the network uses secure communication and, if secure communication is used, examines the configuration file to determine whether it includes a shared secret as shown in step 426. The shared secret may be an encryption key such as a WEP or WPA key. If the shared secret exists, the new device initiates secure communication, e.g. WEP, or WPA with the host or other network devices as shown in step 428. If the shared secret does not exist and the network configuration data does not specify a security protocol, the new device 204 attempts to communicate with the host 202 or other network device over an unsecure channel as shown in step 430.
Once network communication is initiated, the new device 204 accesses any data stored on the network that is identified in the known sources portion of the configuration file 216. For example, if the new device is a radio tuner, it accesses data at a path identified in the configuration file, e.g. “\mymusic\presets.” The data in the location identified by the configuration file is then used to configure the device.
The method 400 is repeated for each new device to be configured and/or added the network. The host 202 may save the specific configuration file created for the new device 204. This facilitates reconfiguration of the new device 204 should it lose its configuration. Additionally, the user may update user information or preferences. By way of example and not limitation, the user changes the list of preset channels to be used with radio receivers. The method 400 is then repeated to reconfigure the new device 204. Alternatively, the new device 204 is programmed to periodically check the configuration information on the network and automatically updates its configuration without the need for user intervention.

The multi-connector storage fob 500 includes a housing 502, a first connector 504 and a second connector 506. The housing 502 is made of any suitable material, one example of which is plastic. The housing is further any suitable shape and size, but is preferably small enough to be hand held so as to maximize its portability. The multi-connector storage fob 500 further includes electronic circuitry and components within the housing. The electronic circuitry includes a controller 508, a memory 510, and a first switch 512. The multi-connector storage fob 500 also optionally includes a second switch 514.
The controller 508 is any suitable microprocessor or microcontroller. The memory 510 is one or more types of volatile or non-volatile memory, examples of which include RAM, EEPROM, and Flash Memory. The electronic circuitry is communicatively coupled to the first connector 504 and the second connector 506 through the first switch 512.
The first and second connector 504, 506 are any suitable type for providing an electrical connection. Examples of known types of connectors include A-type USB, B-type USB, mini-USB, PCI, serial port connector, and parallel port connector, to name a few. Alternatively, one or both of the first and second connectors 504, 506 provide a wireless interface, such an RF or infrared interface. Preferably, the first and second connectors are different types. For example, the first connector is the A-type USB connector, while the second connector is the mini-USB connector. Having the first and the second connectors 504, 506 be of different types increases the variety of types of new devices and hosts that can be used with the multi-connector storage fob 500. For example, the host may include the A-type USB port while the new device 204 includes the mini-type USB port.
The first switch 512 is an electronic switch that only permits one of the first or second connectors to be active, i.e. in communication with the electronic circuitry at any given time. When one of the first or second connectors is interfaced to the host 202 or the new device 204, the first switch 512 electronically disconnects the other of the first or second connectors from the electronic circuitry. Any suitable electronic switch is used to implement the first switch, such as a transistor, relay and the like.
In an alternative embodiment, the first switch 512 is implemented with an electromechanical switch. For example, the first switch 512 is implemented with a slide switch, toggle switch, or the like. When the slide switch is in a first position, the first connector is active, i.e. electrically interfaced to the electronic circuitry in the storage fob. When the slide switch is in the second position, the second connector is active.
In another alternative embodiment, the first switch 512 is implemented such that it physically prevents both the first and second connectors from being interfaced to external devices at the same time. For example, the first switch 512 is implemented as a sleeve slideably mounted onto the outside of the housing 502. The sleeve is dimensioned such that when one of the first or second connectors is exposed, the other connector is mechanically covered so as to preclude both the first and second connector from being physically interfaced to other devices at the same time. In this embodiment, the electronic circuitry is coupled directed to the first and second connectors.
The first switch 512 is used to prevent damage to the multi-connector storage fob 500 that may otherwise occur if both the first and second connectors are simultaneously connected to different electronic devices. Accordingly, it will be appreciated that if one or both of the first and second connectors provide a wireless interface, the first switch is not required and is optionally not included as part of the multi-connector storage fob 500.
The optional second switch 514 is any suitable mechanical switch, such as pushbutton, slide switch or toggle switch. Alternatively, or in combination with the mechanical switch, the second switch is a biometric device such as a finger print reader. The function of the second switch is to indicate a setting, such as administrative, user, or guest, that is used to select one useable configuration file from a set of useable configuration files. The second switch is interfaced to the electronic circuitry such that its position or other information provided by the switch can be read and processed by the controller 508.
The host 202 includes a system bus 121 (
In a second step, the new device 204 initiates a plug and play (PnP) enumeration phase 604. The PnP enumeration phase 604 is a known process that need not be described in detail herein. Briefly, however, PnP enumeration is a process that provides for automatic and dynamic recognition of installed hardware. During the PnP enumeration phase, the new device 204 announces its presence by sending, to the host 202, data such as a product identifier. A PnP manager at the host 202 receives the data from the new device 204 and determines which drivers are required to support the new device 204. The host 202 then loads any such required drivers. The PnP manager also notifies any processes that have registered to be notified of corresponding PnP events, such as device registration.
In a third step, the host 202 transmits a query 606 to the new device. The query 606 includes a request for the wireless capabilities of the new device 204. In a fourth step, the new device 204 provides a response message 608, which includes the wireless capabilities of the new device 204. Examples of wireless capabilities include the type of wireless networks supported, e.g. 802.11, authentication and security methods supported, e.g. WEP, WAP and the like, as well as other information such as manufacturer, model, firmware version and the like.
After receiving the wireless capabilities of the new device 204, the host 202 creates a profile 610, which includes a set of wireless settings. The wireless settings include parameters to be used by the new device 204 for network communications. Examples of the parameters in the wireless settings include identification of a protocol, e.g. WEP or WAP, cryptographic key, and network identification, e.g. SSID. If the new device is a wireless access point, the wireless settings also include a mode. The mode identifies how the wireless point will function, e.g. as a wireless access point, point-to-point bridge, point-to-multipoint bridge, or wireless client.
Any suitable mechanism is used to create the profile 610 and the wireless settings included therein. For example, the wireless settings are entered by a user via a Graphical User Interface (GUI). Preferably, the user enters the wireless settings after viewing the wireless capabilities of the new device via the GUI so that the wireless settings are consistent with the device's wireless capabilities, e.g. identify a wireless network type and security protocol that the new device is capable of using. Alternatively, the wireless settings are automatically selected based on a set policy. For example, the policy may require using secure communications and further using a cryptographic key having a certain number of bits. If the new device 204 is not capable of network communication according to the policy, the host may elect not to configure the new device 204 in which case the method 600 is terminated.
After the profile 610 is created for the new device, the set of wireless settings therein are transmitted to the new device 204 in a message 612. After receipt of the message 612, the new device 204 configures its settings according to the wireless settings in the message 612. If the new device successfully configures its settings according to the wireless settings, a confirmation message 614 is optionally sent from the new device 204 to the host 202. Wireless communication via the network is then initiated as shown in step 616.
The new device 204 optionally implements security measures after the new device 204 is connected to the system bus. For example, if the new device 204 is a wireless access point, the wireless network is disabled to prevent unauthorized access to the network before secure communication (e.g. WEP or WAP) is enabled. Further, if the new device 204 includes an interface to an external network, such as the Internet, the interface to the external network is disabled. Disabling the interface to the external network provides another way to prevent unauthorized access to the network and to the new device 204. After the method of
