I have a similar bug on Maverick on a 5,1 Macbook Pro Up until a couple of days ago the camera would work most of the time, but now it's completely unrecognized by the system (the i.e. /dev/video0 device is never created) although it works perfectly on OSX.
Firmware loading doesn't seem to be the issue because according to my research the camera's USB ID of 05ac:8507 would only appear after the firmware was loaded. Doing sudo modprobe uvcvideo trace=15 spits out lots of debugging info, but it all looks OK except for this bit: uvcvideo: Scanning UVC chain: OT 2 uvcvideo: Found reference to unknown entity 170. uvcvideo: No valid video chain found. I looked around the driver source code for the error but couldn't find out why it's erroring out. So, pretty annoying that the camera's not working, because it worked flawlessly on karmic. Just let me know how I could help out getting to the bottom of this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/544469 Title: iSight webcam on Macbook Pro does not work -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
