It's happened most frequently on the bus to which my mouse is attached. It's been completely random so far - it'll happen for no apparent reason while I'm using my workstation, particularly the mouse. The only workaround I've found so far is to reboot or plug the affected device(s) into a different USB port. Any ideas if this is a hardware issue or a software bug? Anyone have suggestions to try reproduce the problem? Any point even spending time on this with USB2 'round the corner? Thanks, Aragon
