Comment 32 for bug 185634

The uvcvideo module that is in l-u-m is fine and has been working for awhile. That is the only part of Ubuntu this relates to.

Have you tried re-extracting the firmware? uvcvideo seems to be rejecting the firmware load for some reason which means the previous issue is fixed since it wasn't even trying to load firmware with the old version.

I think you may have a slightly different problem. Can you try with a different version of AppleUSBVideoSupport
