We've noticed similar problems with Creative Optia AF camera.  Usually it's the 
first 1 or 2 frames from when capturing begins but I've noticed it can happen 
from the 10th frame.  (We were trying single frame captures from the mjpeg 
stream, capturing 10 frames and saving the last)   Either the start of the 
mjpeg frame was missing (I think from different offsets) or frame was truncated.

The best thing we could do was to check for a valid jpeg header before saving 
the frame.  (although sometimes the tail image data was incorrect, that was 
harder to diagnose without parsing the entire mjpeg frame)

Assuming the drivers are correct, I suspect maybe the camera starts dumping to 
a frame buffer without checking for errors.

We were using revision 189 of the drivers, which was fairly recent at the time.

Hi,
  I'm newbie, but I have a web cam which doesn't work today either
with uvc driver, either with the gspca driver.
  It is a Sonix webcam (SN9C110).
  However, I want to make it work, I don't know if it is possible.
What should I do to start? Where to look out?
  I have looked into the code and I have seen few specifics hacks for
some webcam. There is any way to identify if this webcam needs some
hacks too?
  Thanks in advance,
                           Jordao
