Device for Interfacing Universal Serial Bus enabled devices with Microdrives

Disclosed is a device that can be used to store digital pictures from a digital camera (or another device) equipped with an USB. The device can transfer pictures from the camera to the device or viceversa if allowed by the camera. The device can also be used to transfer the pictures to/from a computer. The device comprises an IBM* 1 Gb Microdrive (the one used on the IBM PCMCIA Microdrive card), together with one basic PC-in-a-chip embedded system and two USB conectors. One of the connectors (slave) is used to download/upload media from/to the device. The other connector (Master) is used to communicate with a computer, in order to manage the media in the Microdrive. The device has three buttons and a very basic LCD display for human interfacing. It uses Linux as operating system in order to support USB file systems, the common vehicle used by most USB storage devices. This device is highly portable as it is not bigger than a digital camera (the exact measurements have not been calculated yet as they depend on the material used). Usability is also very high as the way to transfer the media into it is very straightforward, requiring only to connect the device to the USB port of a camera/device and navigate through the data in the camera/device using the display and the buttons on the front panel. The device will support any camera/camcorders that are advertised as an USB storage device (currently more than 160 digital cameras) and can also be 'instructed' to recognize 'non-standard' devices by installing the corresponding Linux drivers. Similarly, the device will apper to a computer as a Storage device (removable hard disk) with directories and files. This device is cheap enough to be built and sold at a price that can compete with Digital camera storage systems, holding a capacity from 1Gb up, instead of the typical 8-256 Mb of sticks. The display is a basic LCD like the one used on calculators, digital watches or mobile phon...
