Most recent kernel where this bug did not occur:2.6.18
Distribution:debian
Hardware Environment:i686, quickcam messenger logitech
Software Environment:xawtv, vmware
Problem Description:
when I plug my quickcam messenger webcam and try to get the video with a software like xawtv all I get is a black screen. The cam works perfectly with previous version of the kernel. I tried with the 2.6.22 kernel and I had the same result. I also tried to compile the driver from the source and to delete the module from the  kernel and I still had a black screen.

the error message from xawtv is the following:

This is xawtv-3.95.dfsg.1, running on Linux/i686 (2.6.22-rc3-686)
