This used to work in pre-2012 distros 'out of the box' but no luck with any of the main distros this year. The cam is integrated into a Dell LCD and lsusb shows its ID as:
Bus 003 Device 004: ID 05a9:264a OmniVision Technologies, Inc.
uvcvideo is loaded but the device just isn't recognised -- cheese, skype, UCView and Camorama all fail.
Just trying Fedora 17 after a long break and I'm impressed, but could do with this working. Any ideas anyone?
