After looking better at the code I found that file
"cpu/mips/au1x00_usb_ohci.c" is derived from
"cpu/arm920t/at91rm9200/usb_ohci.c". The differences are very minimal
so I think the problem is during USB controller setup...


   (Re)start USB...
   USB:   scanning bus for devices...
         USB device not responding, giving up (status=20)
   2 USB Device(s) found
          scanning bus for storage devices... 0 Storage Device(s) found

so I think that the system found the USB key but cannot connect with
it. In fact removing the USB pen the system say "1 USB Device(s)

May someone help me in understanding why this happens? I'm not a
OpenHCI guru :) and perhaps some good suggestions may help me in
finding the solution!

Thanks in advance,
