Bug 1996 - Contribution for West Bridge Astoria Symbian Storage Driver
this storage driver is for the West Bridge Astoria chipset. This device
has a USB, SD and processor port for communication with a baseband processor.
In our port, we connected this device DVK to the Beagleboard through the SPI
interface of the OMAP3. After driver installation, the Symbian OS can see an
external device or D: drive represented by the SD card. In this driver, the USB
interface is not used directly, though this may be the subject of future
contributions. The appropriate way to test the driver is to access the external
volume and do file read and write to it, pretty much the same way you would
test a thumb drive on your PC
