now not works....
I start cheese and I view: http://sacarde.interfree.it/errore-cheese.png
and this messages:
Cheese 2.28.1

Found device 0471:0322, getting capabilities...
Detected v4l2 device: USB Camera (0471:0322)
Driver: sunplus, version: 132864

I have

ls -l /dev/video0
crw-rw---- 1 root video 81, 0  4 gen 09:51 /dev/video0

may be a policykit.conf problem?

Re: problem webcam gspca

Are you part of the video group?

If that doesn't work try installing libv4l, and (if it still doesn't work) run

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so cheese
