trying uvccapture I get the following:

/uvccapture-0.4 # ./uvccapture -v
Using videodevice: /dev/video0
Saving images to: snap.jpg
Image size: 320x240
Taking snapshot every 0 seconds
Taking images using mmap
Unable to set format: 22.
 Init v4L2 failed !! exit fatal


modprobing with trace=15 I get the following:
