Not necessarily on his system, though.  Every day on this FC6 box my logwatch 
report tells me

usb 1-1: device not accepting address 2, error -71 ...:  1 Time(s)

I see it as I boot up, and sometimes another similar one - usb-5-1, IIRC.  
They haven't caused me any problems at all.

I know that I'm not alone in seeing these - I've seen others mention them on 
the lists.
