quickcam pro 4000 works on hardy but not karmic

[lunkwill]

Binary package hint: cheese

This is a bug in v4l2, not cheese, but I couldn't find the appropriate package. Can you redirect it?

My quickcam pro 4000 works great on my hardy machines, but only sometimes on karmic. The webcam is detected, but won't show any video on cheese or the v4l2 capture.c sample code.
