Hi Marten!

I see some CRC errors there, indicating some kind of cable problem:

TD(0xc4a9c860) td_next=-VF td_status=-CRCTO-STALLED, errcnt=0, actlen=8 
TD(0xc4a9c830) at 0x0269c834 = link=0x00000001 status=0x398003ff 
token=0xffe80269 buffer=0x00000000

Try the following patch:


Not sure if it helps.

Also try to use an external USB HUB.
