Webcam module pwc in 2.6.17-10-generic doesn't work

[Christoph Langner]

Hi There!

I use a Philips PCVC740K webcam on my computer. The webcam works with
dapper out of the box. But Edgy is a little bit more trouble. Right now
i have an up to date Edgy Eft with following kernel

# uname -r
2.6.17-10-generic

When i connect the webcam via USB to my computer /var/log/messages shows
this

# tail -f -n 0 /var/log/messages

Oct  1 17:27:40 isleofskye kernel: [17198463.184000] pwc Registered as /dev/video1.

So the webcam is recognized and should work under /dev/video1. But when
i try camorama with

# camorama -d /dev/video1

or camgrab

# camgrab -device /dev/video0 -output /home/toff/Desktop/test.png

i only get a grey picture. Nothing else. Just a plain gray picture. So i
got the latest pwc driver from

http://www.saillard.org/linux/pwc/files/

compiled and installed the kernel module and the camera works. In my
eyes it looks like the pwc kernel modules in edgy is broken.

Thanks
