QuickCam Orbit AF Pan/Tilt Broken in Sid
Hi all,
I have a Logitech QuickCam Orbit AF (USB ID 046d:0994). The Pan/Tilt controls work fine under Debian Squeeze, but they fail under Debian Sid.
When I plug in the camera, udev runs uvcdynctrl to load the pan/tilt controls into the driver. On Debian Squeeze, this works OK, but here is what happens on Debian Sid:
Executing command: 'uvcdynctrl -d /dev/video0 --addctrl=046d:0994'
[libwebcam] Unsupported V4L2_CID_EXPOSURE_AUTO control with a non-contiguous
range of choice IDs found
[libwebcam] Invalid or unsupported V4L2 control encountered: ctrl_id = 0x009A0901, name = 'Exposure, Auto'

/usr/share/uvcdynctrl/data/046d/logitech.xml: error: device 'video0' skipped because the driver 'uvcvideo' behind it does not seem to support dynamic controls.
In an attempt to narrow down the problem, I rebooted my machine to the Squeeze kernel (2.6.32-5-686-bigmem), and the error message changed:
Importing dynamic controls from file /usr/share/uvcdynctrl/data/046d/logitech.xml.

I downgraded libwebcam0, uvcdynctrl, and uvcdynctrl-data to the versions in Squeeze. At this point the pan/tilt controls started working OK. When I rebooted back to the current Sid kernel (3.2.0-2-686-pae), I got the original error again. This leads me to believe there is a problem with the kernel, but I wanted to try asking here before filing a bug report.
Has anyone else encountered this problem? Any thoughts on what I should try next? I can't use 2.6.32 for day-to-day operations, so I'm kind of stuck in a bind.
Please CC me as I'm not subscribed to the list.
Cheers,
Mike.
