Just wanted to pass on how I fixed my Logitech Quickcam 3000 for Business (046d:09a5 from dmesg) in Mint Helena (2.6.31-14-generic) and Skype... Quite simple in the end... Annoyed me that it wasn't working cos I bought it specifically cos I read somewhere that it would work perfectly. With the last version of Skype, I had to start Skype with a command line that incorporated video settings like "bash -c ‘export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype’" or "bash -c ‘export LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so; skype’" ... Anyway here's what I did:
1. sudo chmod 777 /dev/video0
2. Download and install latest Skype beta (126.96.36.199)
-- The webcam was working at this point, but the colours were awful
3. install luvcview from the repositories, and run it
4. Hit the button near the middle for 'reset all to defaults'
Hope this helps someone.
