Ok, the new patch worked :)

So far so good...

I opened Kopete, and it was working. I closed Kopete, re-opened it, and got 
mangled video...

gambit trunk #dmesg
<snip>
uvcvideo: Failed to query (130) UVC control 1 (unit 0) : -32.
uvcvideo: Failed to query (1) UVC control 1 (unit 0) : -32.
uvcvideo: Failed to query (1) UVC control 1 (unit 0) : -110.
uvcvideo: Failed to query (1) UVC control 1 (unit 0) : -110.

Then I waited a few seconds...
usb 1-1: reset high speed USB device using ehci_hcd and address 2

...and the video went back to normal! This patch gets my vote.
