Description

FIELD OF THE INVENTION

The present invention relates to memory drives, and more particularly, to smart USB modules and smart USB devices.

BACKGROUND

Memory drives such as USB drives are frequently used for data storage and the transferring of electronic data between computers or devices. Conventionally, USB drives act as a client and are considered “dump” devices that require plugging into a computer or device with an USB port (“host computer”) to enable data transfer from the host computer to the USB drives or from the USB drives to the host computer. Therefore, conventional USB drives require a host computer to function and the data cannot be accessed instantly as needed until a host computer is available, for example at home or at the office. Therefore, there is a strong need for a solution that overcomes the aforementioned issues. The present invention addresses such a need.

FIG. 6 illustrates a diagram 600 of automatically switching a smart USB device between a plurality of functionality configurations in accordance with an embodiment. The diagram 600 includes an USB drive 602 coupling to a smart USB module 604 to provide a smart USB device 606. By default, the smart USB device 606 is automatically switched to perform the functionality of an USB drive 602 when plugged into an USB host port 608a of a computing device 608. In this first functionality configuration, data transfer between the computing device 608 and the USB drive 602 is enabled via non-wireless communication.

When the smart USB device 606 is wirelessly connected to a portable device 610 (e.g. smartphone, tablet, etc.) via a setup and configuration process, the smart USB device 606 is automatically switched to a second functionality configuration that performs the functionality of the smart USB device 606 and enables wireless transmission and communication of data between the smart USB device 606 and the portable device 610.

In one embodiment, the portable device 610 is in communication with (or connected to) a public cloud 612 thereby enabling data stored on the smart USB device 606 to be wirelessly accessed by the portable device 610 and then transferred and/or communicated to the public cloud 612 for any of storing, viewing, and analyzing. In one embodiment, the smart USB device 606 is directly connected to the public cloud 612 via a setup and configuration process thereby allowing the portable device 610 to access, transfer, download, or upload data to the public cloud 612 via the smart USB device 606, or to access, transfer, download, or upload data stored to the smart USB device 606. In another embodiment, the public cloud 612 is a private cloud computing environment.

When the smart USB device 606 is wirelessly connected to the portable device 610 (and potentially connected to the public cloud 612 via any of a direct connection and a connection established by the portable device 610), data stored on the smart USB device 606 can be accessed, transferred, downloaded, and/or uploaded by any of the portable device 610 and the public cloud 612, and data stored on any of the portable device 610 and the public cloud 612 can be uploaded to the smart USB device 606.

In one embodiment, the computing device 608 is also portable but the connection with the smart USB device 606 is direct (e.g. the smart USB device 606 is plugged directly into an USB host port 608a of the computing device 608) and therefore not a wireless connection. Therefore, even if the computing device 608 is portable, when the smart USB device 606 is plugged directly into the computing device 608, the smart USB device 606 is automatically switched into the first functionality configuration. In another embodiment, the smart USB device 606 is wirelessly connected with a non-portable device (e.g. mainframe of servers) and the smart USB device 606 is automatically switched into the second functionality configuration.

In one embodiment, when the smart USB device 606 is connected (e.g. directly, wirelessly, via other means) to any of a computing device 608 and a portable device 610, a prompt is generated to enable the manual switching of the smart USB device 606 between configurations that default USB drive 602 functionality, smart USB device 606 functionality, and any other functionality configuration.
