Greetings,
I have been working with Paulo Assis on the quickcamteam forums. We have been trying to determine why a Logitech Orbit MP 046d:08c2 is not responding to Pan (relative) or Tilt (relative) controls. Pan/Tilt reset and all other Logitech specific controls work splendidly despite this. The thread with the details is here: http://forums.quickcamteam.net/showthread.php?tid=685 I noticed on the uvc driver home page http://www.ideasonboard.org/uvc that the 046d:08c2 is listed as being compatible with no mention of these controls being unusable (albeit potentially unreliable with the footnotes). We are unable to get past the camera reporting that it failed to query the control. Interestingly enough pan and tilt functions work fine on any supported Windows OS using available pan/tilt control software. We are thinking that perhaps the reason for this is that the uvcvideo driver expects to query these controls prior to setting their values (and fails to read), as opposed to the working windows drivers which (perhaps aware of this firmware issue) do not query the controls, rather just attempt to set their values. dmesg uvcvideo trace=15 on module insertion -snip- [ 1449.492454] USB Video Class driver (v0.1.0) [ 1449.732361] uvcvideo: Control f70c9e90/2 is already defined.
