Package: linux-image-2.6.29-2-686
Version: 2.6.29-5
Severity: normal

The new GSPCA in the kernel mainline dropped support for this webcam and probably more since 
inclusion:

ID 0ac8:303b Z-Star Microelectronics Corp. ZC0303 WebCam

There's a C-hardcoded "KConfig" #ifdef in the respective GSPCA chipset module which 
passes handling of this cam to the legacy zc0301 driver but it cannot support it:

Jun  9 16:33:11 tom2 kernel: [ 1086.990379] usbcore: registered new interface driver zc0301

I can remember fixing this months before but did not submit the patch for some reason... nor can I find it 
anymore up to this time.
It worked but the new gspca v4l2 main has dropped other useful things like the brightness/contrast/color 
module parameters, so it was useless to me with applications not supporting v4l controls like 
adobe flash + flashcoms video chat.

Thanks, closing the bug, then.
