I know this is luv-main; but are you sure this is not some kind of USB networking thing?;
The USB drive was plugged directly into the computer, so I doubt it... Could another USB device plugged into another port interfere? Have been assuming no, maybe I shouldn't be making this assumption? I have my keyboard/mouse plugged into a hub built into my monitor. They seem to work fine, even after the crash. Somebody else asked me for the output of lsusb, here it is: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc.
