Debian Sid with this webcam require not specific drivers but new codecs!
Use this command to install Gstreamer with the right packages and codecs:
apt-get install gstreamer0.10-alsa gstreamer0.10-ffmpeg gstreamer0.10-fluendo-mp3 gstreamer0.10-plugins-base libgstreamer-plugins-base0.10-0 libgstreamer0.10-0 libgstreamer0.10-dev gstreamer0.10-plugins-good gstreamer0.10-plugins-ugly gstreamer0.10-plugins-bad gstreamer0.10-tools
This webcam render directly in H264 then installing these codec fixes the problem.
