3.0 mega pixel USB UCAM-DLX300B Series (Windows and Mac)

I tried the following on Ubuntu 9.10:
* Didn't work at all using cheese 2.28.1. Found the device, couldn't detect the
resolution, no picture - the screen is colored stripes.
* Worked immediately in (gui) vlc 1.0.2, using YUY2 codec, can only get a 
resolution
of 640X480. I did not find a way to change the resolution using vlc command line
parameters. Tried something like the following:

vlc v4l2:// :v4l-vdev="/dev/video0" :v4l-adev="/dev/audio2" :v4l-norm=3
:v4l-frequency=-1 :v4l-caching=300 :v4l-chroma="" :v4l-fps=-1.000000
:v4l-samplerate=44100 :v4l-channel=0 :v4l-tuner=-1 :v4l-audio=-1 :v4l-stereo
:v4l-width=1280 :v4l-height=720 :v4l-brightness=-1 :v4l-colour=-1 :v4l-hue=-1
:v4l-contrast=-1 :no-v4l-mjpeg :v4l-decimation=1 :v4l-quality=100

* Using brown-ros-pkg probe node:
$ rosrun probe probe
Gstreamer Version: GStreamer 0.10.25
stream is PAUSED.
libv4l2: error converting / decoding frame data: v4l-convert: error parsing JPEG
header: Not a JPG file ?

I also checked the permission and group settings on /dev/video0.

Possibly giving up ...

Only thing I can think of is to hook it up to a Windows or Mac and have it 
stream images 
like a sort of home-brew GigE cam.  Can we get high res on the mini?

I did find some discussion online that this camera (0ac8:3420 Z-Star 
MicroElectronics
Corp) might work on linux after a kernel update, but I found no guarantees.

Low resolution does work on linux and mac. We have decided to use this camera 
for low
resolution work.
