is your usb not working?
You shouldn't need any USB driver for this board.
usb is working but its working at 12mbps maximun which is maximum speed for usb 1.1 but usb 2.0 works 30mbps speed
maybe there is a bios setting configured to run the usb at 'full speed' and not at 'high speed'.
btw, usb 2 runs at 480mbps.
