I already have a webcam, a Logitech Quickcam Express. It is a few years old. I have tried to install it, but without any sucess. The product ID is 0840 and the vendor ID is 046D. I am currently running Ubuntu Karmic Koala 9.10. According to the Ubuntu Wiki the qc-usb driver should work, but I could not manage to get it to compile. Any suggestions would be gratefully received.
