The present invention relates generally to memory storage devices and more specifically to the management and identification of such devices.
There are a variety of environments where memory devices are coupled to a host system to allow for the display of their contents on the screen of the host device. The memory device such as a USB device can be directly coupled onto the host system through a connector. When it is desired that several of the memory devices be connected to the host system a hub is utilized. A typical hub is a standard 4-port USB hub but there are other types of hubs as well.
This type of hub cannot be managed in terms of individual ports. That is, when a USB device is inserted to the USB port, it is automatically detected by the OS. Application programs will pop-up on the computer screen, and these can be accessed by users.
This can be problematic in a couple of areas. First as the number of devices connected to the hub increases the user might want to know what is on the hub before it is launched. To be able to identify what is on each device would be helpful in managing and organizing the information. Furthermore there may be for example malicious viruses, malware or the like on a particular memory device that is connected to the hub. Therefore minimizing the launching of such applications onto the host system is also highly desirable.
Accordingly what is needed is a system and method that identifies the above-identified issues. The system and method should be cost effective, easily implemented and adaptable to existing environments. The present invention addresses such a need.
A management hub is disclosed. The management hub comprises an interface; a master hub controller coupled to the interface; a plurality of ports coupled to the master hub controller; a microcontroller coupled to the master hub controller; and a slave hub controller coupled to the microcontroller and the plurality of ports. The management hub also includes a memory device coupled to the microcontroller, the memory device including a hidden drive information partition and a hidden drive organizer partition for managing and identifying information in various drives coupled to the plurality of ports, wherein when the management hub is first connected to a host system the drives are displayed in an inactive state.
A system and method in accordance with the present invention manages and identifies multiple flash memory storage devices that are inserted into a management hub in the following ways:
(1) Isolating each Flash memory storage device in an “Inactive State” so it is only visible to the host PC through the—Drive Organizer Management Console (DOMC) from the management hub, thus blocking “OS” from the host PC from accessing the flash memory storage device.
(2) Allowing each Flash memory storage device to be placed in an “Active State” where the device can be enumerated by the host PC and accessed by any application such as Windows Explorer.
(3) Easily updating and viewing the device name.
(4) Supporting a memo for adding description to each device. This memo is stored in the onboard memory and can be easily viewed and updated by the user. Each memo is uniquely associated to the corresponding flash memory storage device.
(5) Easily launch the Windows Explorer application. Double clicking on any of the flash memory storage devices in the DOMC that are in the Active State will launch Windows Explorer to the corresponding device.
(6) A casing can also be used to store the management hub and at least one flash memory storage device.
The present invention relates generally to memory storage devices and more specifically to management and identification of such devices. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements. Various modifications to the preferred embodiments and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features described herein.
A system that utilizes a management hub in accordance with the present invention can take the form of an implementation of entirely hardware, entirely software, or may be an implementation containing both hardware-based and software-based elements. In one implementation, this disclosure is implemented in software, which includes, but is not limited to, application software, firmware, resident software, program application code, microcode, etc.
Furthermore, a management hub of the present invention can take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system. For the purposes of this description, a computer-usable or computer-readable medium can be any apparatus that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. Further a computer-readable medium includes the program instructions for performing the steps of the present invention. In one implementation, a computer-readable medium preferably carries a data processing or computer program product used in a processing apparatus which causes a computer to execute in accordance with the present invention. A software driver comprising instructions for execution of the present invention by one or more processing devices and stored on a computer-readable medium is also envisioned.
The medium can be an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system (or apparatus or device) or a propagation medium, or a signal tangibly embodied in a propagation medium at least temporarily stored in memory. Examples of a computer-readable medium include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM), a read-only memory (ROM), a rigid magnetic disk, and an optical disk. Current examples of optical disks include DVD, compact disk-read-only memory (CD-ROM), and compact disk—read/write (CD-R/W).
Each of the ports 116a-116f is coupled to a multiplexer 118a-118f. Each of the ports 116a-116f can also be coupled to a drive and/or hub 100. Each of the six ports 116a-116f has a status light emitting diode (LED) 120a-120f. In one embodiment, the status LEDs 120a-120f indicate the following states of the device:
By default, each management hub will assume the name such as DT Organizer and can be modified by users. The name is stored in the hidden area of the onboard flash memory 114 and is displayed at the top of the DOMC 113. Right clicking on the name in the DOMC 113 allows the user to edit the name of the management hub 100. This allows for easier management when multiple management hubs 100 are connected to the same host PC 102.
The management hub 100 can support multiple management hubs in a cascading/serial connection.
Double clicking on a port that has another management hub connected causes the DOMC to set focus to that management hub connected to that port.
The management hub can also support multiple management hubs 100a″-100c′ in a parallel connection with the host computer 102″.
If multiple management hubs are connected, either independently or by cascading, clicking on the DOMC in the system tray displays a popup with all the names of the management hubs 100a″-100c″ or 100a′-100c′. Clicking on a particular name sets the DOMC to focus on that particular flash memory storage device.
The DOMC 300 shows all six ports 304a-304f. When the left click is activated, the drive capacity 306 and usage 308 is displayed. Inactive drives 302 are gray-out and displayed as gray (or any other colors) drive 1 and drive 4, in this example. For each drive, the port number 310a-310f is displayed. The volume label is displayed in the name field 312. A portion of the drive description 314 is displayed in the description field. The description is the memo field.
If a drive is removed, the DOMC 300 software identifies the port as Drive Not Present
Any subsequent connections of a flash memory storage device to the management hub show the device as Inactive and the DOMC 300 is updated. Whether the drive is active or inactive, the user is always able to read and modify the drive volume and descriptive field through the DOMC 300. Third party flash memory storage devices function with the same behavior as company flash memory storage devices, such as those manufactured by Kingston when connected to any of the six ports of the management hub. Non-storage devices function normally as if they were connected to standard ports. Windows Explorer or any other application sees and accesses only the active drives. The DOMC 300 software can also be launched by navigating to the read-only partition by clicking on the application.
By default each management hub will assume a name such as, for example, DT Organizer, and can be modified by users. This name is stored in the hidden area of the onboard flash memory and is displayed at the top level of the DOMC 300. Right clicking on the name in the DOMC 300 allows the user to edit the name of the management hub. This allows for easier management when multiple management hubs are connected to the same host PC.
Double clicking on a port that has another management hub connected will cause the DOMC 300 to set focus to that management hub connected to that port.
For multiple management hubs in parallel connection with the host computer, the DOMC 300 allows for at least two independent management hubs connected to the host system through independent ports.
If multiple management hubs are connected, either in parallel or by cascading/serial, clicking on the DOMC 300 in the system tray displays a popup with all the names of the management hubs. Clicking on a particular name sets the DOMC 300 to focus to that device.
When one of the flash memory storage devices are inserted into the management hub via step 602, depending on the hub setting from DOMC, via step 604, if it is set for a managed hub via step 606, it will check to see if it is an HID device via step 608, e.g. keyboard, mouse, webcam. If it is not an HID device, then the flash memory storage device is in an inactive mode, via step 610. If it is set for an unmanaged hub, then the DOMC is bypassed, and the flash memory storage device is always in the active mode, via step 612.
When the management hub is first connected to a PC, the DOMC can be launched by clicking to the application, via step 614. If the application is closed by clicking the “X”, via step 616, it checks to see if the flash memory storage device is busy, via step 618. If yes, it remains active in the system tray. If the device is not busy, then the application is closed, via step 620. Any flash memory storage devices that are connected to the management hub are displayed in the DOMC in the inactive state.
The DOMC shows all memory storage devices that are inserted into the management hub's ports. With the right click, via step 622, the drive capacity and usage is displayed. Inactive drives are displayed as gray, via step 628 (or any other colors). For each drive, the port number is displayed. The volume label is displayed in the name field. A portion of the drive description is displayed in the description field. The description is a memo field. Right clicking on the name in the DOMC allows the user to edit the name of the management hub, via step 630. This allows for easier management when multiple management hubs are connected to the same host PC. After the information has been changed, it will save the changes, via step 632, and update the status, via step 634, from the DOMC.
Any subsequent connections of a flash memory storage device to the management hub show the device as inactive and the DOMC is updated.
Whether the drive is active or inactive, the user is able to read and modify the drive volume and descriptive field through the DOMC.
Left clicking, via step 636, will display the detail of the drive information, via step 638.
Double clicking, via step 640, on any of the flash memory storage devices in the DOMC that are in the active state, via step 642, launches Windows Explorer, via step 644, to the corresponding device.
The advantages are:
(1) Isolating each flash memory storage device in an “Inactive State” so it is only visible to the host PC through the “Drive Organizer Management Console (DOMC) from the management hub, thus blocking “OS” from the host PC from accessing the flash memory storage device.
(2) Allowing each Flash memory storage device to be placed in an “Active State” where the device can be enumerated by the host PC and accessed by any application such as Windows Explorer.
(3) Easily update and view the device name.
(4) Supporting a memo for adding description to each device. This memo is stored in the onboard memory and can be easily viewed and updated by the user. Each memo is uniquely associated to the corresponding flash memory storage device.
(5) Easily launch of Windows Explorer. Double clicking on any of the flash memory storage devices in the DOMC that are in the Active State will launch Windows Explorer to the corresponding device.
(6) The casing can also be used to store the management hub and at least one flash memory storage device.
While traditional hubs provide instance access to the user when the device is inserted into the hub, they cannot be managed individually in terms of ports. They also provide no privacy; thus data cannot be protected.
The management hub identifies multiple flash memory storage devices, and it can be managed when the flash memory storage device is inserted into the management hub. Users can decide when and which flash memory storage devices to launch, and also blocking “OS” from accessing the flash memory storage device upon insertion.
Although the present invention has been described in accordance with the embodiments shown, one of ordinary skill in the art will readily recognize that there could be variations to the embodiments and those variations would be within the spirit and scope of the present invention. The management hub in accordance with the present invention can be utilized with a variety of devices such as a cell phone, a PDA, a laptop and other types of integrated circuits. In addition, the ports can be any of a variety of ports such as USB, IEEE1394, PCMCIA, serial or the like. Accordingly, many modifications may be made by one of ordinary skill in the art without departing from the spirit and scope of the appended claims.
