spy camera, cant find a driver

I bought from ebay this http://cgi.ebay.com/Spy-Pen-Camera-DVR-Video-Hidden-Camcorder-HD1280-x-960-/150438781683?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item2306d9a2f3 pen with camera. It cam be used as web camera too but they didnt gave me a CD. I had same problem with a lighter camera too, cant use it as web camera because no drivers.
So what solution i have? i contacted even the chinese producer, but they didnt answer.
Can i use other drivers and try them until i find one?...

 

Thanks. What u mean "of finding this driver as OEM is the one to get it from so keep trying them"? u mean if the driver exist is for china systems or what? what is OEM.

I have asked to 2 chinese sellers the kit instalation and what they sent me was some strange files, who gave errors when i tried to run them...

But my question if i can try other web camera drivers? probably after more tries one ill work. Or is no point to do that?

 

yes windows try to find a driver and next to clock is a baloon "usb camera"

other question is - my nokia6120 take videos qvga 320x240 and are mpeg-4
This pen take avi. video with 1280x960 but the videos i think dont look better, why? i can check the avi. files in proprieties and there is "1280x960" but in mpeg-4 files on proprieties i cant see any details about resolution etc.

But mpeg-4 are better than .avi?
