Leaving a reply for reference: while trying to add support for another
device [1], I noticed that the fix for CVE-2015-7833 [2] contained a
check similar to the one in Zary's patch:

Yes, I've just noticed this. Perhaps, you could try using vlc and/or mplayer (instead of cheese) and also try to use explicit device, i.e. /dev/video1 and/or /dev/video2. But if the driver fails to set alternate setting, then it will never work, right?
