[U-Boot] At91 mass storage device

[E Robertson]

Hi,
I've got a problem recognizing a USB mass storage device on the at91sam9263ek.
I'm not familiar with this interface and I'm hoping someone might be
able to shed some light on it.
I enable debug hoping something might catch my eyes but so far
nothing. At one point I was
unable to reset the port;

DEBUG: roothub.a: 02001202 POTPGT=2 NOCP NPS NDP=2
DEBUG: roothub.b: 00000000 PPCM=0000 DR=0000
DEBUG: roothub.status: 00000000
DEBUG: roothub.portstatus [0] = 0x00120301 PRSC PESC LSDA PPS CCS
DEBUG: roothub.portstatus [1] = 0x00000100 PPS
DEBUG: RET(rh) URB:[ bfd] dev: 1,ep: 0-I,type:CTRL,len:0/4 stat:0x0
cannot reset port 1!?

However, most of the time I get the results below.
Does anyone have any ideas?
