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?
