[Name] UVC_QUIRK_PROBE_DEF [Value] 0x00000100 [Description] 
Don't request the video probe and commit default values. Some cameras don't implement the GET_DEF request for the video probe and commit controls, or even completely crash when that request is received. The uvcvideo driver can then use the current values as default values.
