Webcam Issues on F10

[Richard Heck]

This kind of issue seems to have been reported in other places, but I
thought I'd try here as well in case anyone had some ideas.

I have an HP webcam that works perfectly in F8. On installing F10,
however, it has completely stopped working. I see similar problems in
cheese, skype, kopete, and even uvccapture. When a program tries to
access the cam, I get errors like:

uvcvideo: Failed to query (1) UVC control 1 (unit 0) : -110 (exp. 26).

And other similar things, depending upon the exact program. Kopete is
the worst offender: It freezes and then crashes when you try to open
Preferences.

I've tried fiddling with the permissions on /dev/video0, but to no avail.
