[U-Boot] USB key not recognized

Hi

I am using Atmel AT91SAM9263-EK and running u-boot 1.1.5, it fails to recognize a USB key of size 1GB and formatted in FAT.

This is what is happening:

U-boot> usb start (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

I have tried U-boot version 1.3.4 and see the same issue. I am using U-boot from the linux demo that came with the atmel kit.

Thanks for helping.

Aman.
