I had one like that a couple of years ago, it was cheap Chinese junk that broke within a few uses. The microphone had rubbish sound quality and the resolution was more like 0.5Megapixels.
Look for a webcam that uses a UVC driver as that works straight away in Linux. I've tried a couple of Logitech webcams and they've worked absolutely fine. Ivan -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
