Unplugging the mouse solves the problem. It seems rather strange to me that this would influence it, since It's not used at all... I ran across this thread: http://marc.theaimsgroup.com/?l=linux-kernel&m=107633614409619&w=2 Has anyone some more info on it? Thanks. Please CC me on answers from linux-usb, i'm not on that mailing list. Jan -- omnibiblious, adj.: Indifferent to type of drink. Ex: "Oh, you can get me anything. I'm omnibiblious."
