You're correct, USB support on the AT91SAM9 boards has some unknown
issues. I can reproduce the behaviour you're seing easily here.

Nicolas Ferre (added in CC:) confirmed the problem too (with both the
current U-Boot version and the atmel specific 1.1.5-atmel_1.5 version).
But he is very certain that it did work at some time in the past, with
some USB storage devices.

So it may be a matter of hardware (lo or hi-speed USB storage
devices ?), or a matter of timing somewhere in the driver, I do not
know. The Linux USB stack works perfectly, so this is not a hardware
problem on the AT91SAM9 chip or board.

Somebody needs to debug this, but I didn't found the time to investigate
yet. If you badly need it to work, well, you're welcome to try debugging
it :)

Thanks,
