gspca/pac207 webcam, detected, but doesn't work

I've been fighting with this little toy for some days now.

The initial setup, supposedly went fine. To sum up and save you some reading here's the relevant stuff, it all seems ok so far:

Code:

$ lsusb
Bus 002 Device 003: ID 093a:2468 Pixart Imaging, Inc. Cammaestro 2.5DU/X-EYE/Orite SC-120/ICGear TravelCam/Easy Snap Snake Eye Webcam

Rrrright. However, no single application will work with this critter. I've tried so far mplayer, mencoder, xawtv and spcacat/spcaview. Spcacat gives me:

Code:

$ spcacat

I am rather inexperienced with this kind of gadget, so I have no idea if this is something silly.

Any help is appreciated, thanks everyone beforehand

When I used that type of camera, I had to preload v4l2:

LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so <your program>

For example: LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype

Read about it, may be it helps you.

I've tried it, but it doesn't seem to help.

My main concern is that even the spca tools fail to operate with this camera. But, as said, I know nothing about this. I've tried lots of things that I've found in the net for many days. It's not a big deal, I can just send to RIP the camera, it's more about curiosity than a real need.

Thanks a lot for trying in any case.

If you really want to use camera, I suggest to find uvc compatible. On my OpenSuse works fine.
