I had a similar problem with my last set up but on suse 10.1 I found that I 
could often plug something into a usb socket and it would be recognised and 
would function. If I removed it  and later plugged it in again it wouldn't 
work and there seemed to be no power on the socket. This could be cured by a 
reboot. As this only started happening many many months after I started using 
10.1 I wondered if it was some sort of power save feature that had gone wrong 
or had been interfered with by an upgrade.  It could also have been a board 
fault/compatability problem but I had no problems at all while running a 
knoppix cd.  These were usb1 sockets. A knoppix cd may help you determine if 
your problem is software or hardware related.

Since then I have installed 10.3 on a new pc and haven't had any problems at 
all. The new board is usb2 through out.
