Thanks. It is normal not to be able to query some USB devices when you are not root. Your webcam does appear to be supported, but the driver is not being loaded. What version of Ubuntu do you use?
If you run the following command, does your webcam work correctly? 'sudo modprobe spca5xx' If not, please attach the output of: 'lsmod' -- Web cam dosn't work https://launchpad.net/bugs/88801 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
