AT91RM9200: USB broken?

[Greg Ansley]

No, I don't think this is normal. The messages are exactly the same with 
a known good USB flash drive attached, and the drive is not found.

Same result as far back as 8.0-RELEASE-p4. Since USB works fine on the 
SAM9G20 card I think I will ignore this for now, so as not to delay what 
I am doing.
