I have a modem attached to the USB connector at the moment, so it's a bit tricky to test. Can you (or someone) provide a backtrace to help trace the cause? (and is the panic "don't do that", perchance?) -- Cheers, Jay http://www.evilrealms.net/ - Systems Administrator & Developer http://www.imperial.ac.uk/ - 3rd year CS student
