Public bug reported:

Binary package hint: linux-restricted-modules-2.6.20-9-generic

Driver was already Broken in Edgy, and I had to recompile it, to get the webcam to work (still bas quality after)
In Feisty, the configuration LED from the webcam is always on, I get no messages from the webcam programms (ekiga or camorama) but also no image...

Here the output from dmesg : 
[ 2053.104000] pwc: Philips webcam module version 10.0.12 loaded.
