Comment 3 for bug 241753

With 2.6.27 this stills an issue. Upgraded from 8.04 to 8.10.a5 and then all auto-updates as they came.

$ uname -a
Linux NolarBook 2.6.27-3-generic #1 SMP Wed Sep 10 16:02:00 UTC 2008 i686 GNU/Linux

$ dmesg | grep uvcvideo
[ 13.500023] uvcvideo: Found UVC 1.00 device Laptop Integrated Webcam (05a9:2640)
[ 13.509776] uvcvideo: Failed to query (135) UVC control 1 (unit 0) : -32 (exp. 26).
[ 13.509911] uvcvideo: Failed to query (129) UVC control 1 (unit 0) : -32 (exp. 26).
[ 13.509914] uvcvideo: Failed to initialize the device (-5).
[ 13.510200] usbcore: registered new interface driver uvcvideo

After that, webcam still doesn't work (regardless of what the last line says).

Doing "rmmod uvcvideo && modprobe uvcvideo" solves the problem. And it says:

[ 6717.305615] usbcore: deregistering interface driver uvcvideo
[ 6719.813625] uvcvideo: Found UVC 1.00 device Laptop Integrated Webcam (05a9:2640)

[ 6720.885163] usbcore: registered new interface driver uvcvideo

After that it works. Probablhy the initial suggestion about blacklisted+/etc/modules will work. I'll check later.
