Comment 21 for bug 544469

Seems there's 2 issues here:
1) sometimes occurring independently
May 26 08:41:05 ridgerunner kernel: [ 14.262710] uvcvideo: Unknown video format 32595559-0000-0010-8000-000000359b71

2) sometimes they coincide
May 24 08:48:33 ridgerunner kernel: [ 12.729848] uvcvideo: Unknown video format 32595559-0000-0010-8000-000000389b71

May 24 08:48:33 ridgerunner kernel: [ 12.729865] uvcvideo: No valid video chain found.
May 24 08:48:33 ridgerunner kernel: [ 12.729892] usbcore: registered new interface driver uvcvideo

#1 the video format issue (see bug 544740 listed as a dup of this bug but I think is not)
#2 no valid video chain (this bug and by far the most prevalent)

Both problems seem to be fixed upstream: MacBookPro5,5 with 2.6.34 kernel (note Cheese seg faults so use something else)
