[pwc] only grey images from /dev/video0

["C. Hacker" <>]

Hi everybody,

supposably since my last kernel patch

uname -r
2.6.16.27-0.6-smp

I only get GREY images from /dev/video0, although
v4l-info seems to recognize my camera correctly (see below).

This is the way I installed pwc several times on several computers:
- Download pwc-10.0.11
- cd pwc-10.0.11/ 
- make
- cp pwc.ko /lib/modules/2.6.16.27-0.6-smp/kernel/drivers/usb/media/pwc/
- depmod -a
- modprobe pwc

/home/ich> v4l-info

Does anyone have this problems, too, or has ideas to solve them? I also 
tried other pwc releases but it simply does not work any more...

Thanks for your help
Christian
