That last message is very odd. It indicates something might be wrong with
your camera. Can you post the output from "lsusb -v" with your camera
plugged in and turned on?
Attached. This is with a 2.4.22 kernel, with which the cam works fine. I can boot into a 2.6.0-test8 kernel and redo this if needed.
