[U-Boot] Problems with USB mass storage on at91sam9263

[Paal Bakken]

I also found another non-working stick.... This one was also a first generation USB 2.0 stick.

But anyway - It seems like you guys has done a great job and made usb mass storage useful! A few non-working sticks is good enough for me :-)

Best regards
