Comment 8 for bug 443278

Jonathon, I've put kernel with webcam debug enabled at:

http://people.canonical.com/~cking/443278/linux-image-2.6.31-13-generic_2.6.31-13.45_amd64.deb

It's probably worth downloading and installing this, and then loading the module with all the debug options enabled:

Boot with the webcam not plugged in, then:

sudo modprobe -r pwc

re-load the module with debug turned on:

sudo modprobe pwc trace=255

and then plug on the webcam and start cheese. Then send the dmesg output, e.g.

dmesg > dmesg.txt

and attach dmesg.txt to the log. It may show some reasons why this driver fails in this mode.
