I have the same motherboard and HAD ;) the same problem. I'm now running XP service 
pack 2 but I had the problem both before and after the update.

Problem, to clarify was as follows:
List of six unknown devices in the USB section of device manager (numbers may vary) 
even though NO USB devices or external hubs were connected.

Lastest nforce drivers did not fix. Uninstalling all USB devices from safe mode did 
not fix.

I simply disconnected all the external USB ports, i.e. the front panel and rear panel 
USB ports, from the motherboard

After I rebooted, the remaining ports were all discovered and worked perfectly. I've 
no need for all the ports as I used a hub but in another post I read, the author 
had reconected his external ports and they worked.
