To reproduce... type 'cat /dev/ttyUSB0' and hit control-C. I have tried removing all modules except the USB serial related ones and get exactly the same, so I think the references to 'mousedev' are bogus in the oops (the taint is from the VMWare modules but I get the same without them so I don't think they're affecting anything).
