No image with Logitech QC 4000 (PWC)

Nilium · 08-25-2006, 06:12 PM

Hi all,

I use Gentoo Linux, 2.6.15-gentoo-r1 kernel, and usb-pwc-re 10.0.12_rc1 driver for my Logitech Quickcam Pro 4000. Using gqcam or camstream, all I'm getting is a solid gray screen. I tried to enable the pwc driver as module and built in, as well as v4l support. I've even tried the kernel's driver for the Phillips chipset, but no luck. Has anybody gone through the same situation? Any help would be much appreciated.

Ok I fixed it myself. I needed the patch, which can be downloaded from the driver's homepage.
