I jut bought a G2 from Tower. Often it loses connection to the USB port and sticks won't respond. I've checked the USB ports and there's no issues with any of the 4 ports I've tried. Is this a common issue? Is there a fix for it?

My setup is....

E-Machines AMD 1800
736G RAM
PrioSavage DDR S3 graphics
SoundBlaster Audigy2

Any thoughts?

EDIT:

I forgot, it's running Windows XP SP2
