Unsupported V4L2_CID_EXPOSURE_AUTO control

[Scott Dylewski]

I keep getting these errors when trying to set parameters using libwebcam and uvcdynctrl:

scott@feynman:/home/weather$ uvcdynctrl -d video0 -g 'White Balance Temperature'=10000
[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'

[libwebcam] Unknown V4L2 private control ID encountered: 0x0A046D04 (V4L2_CID_PRIVATE_BASE + 33844484)
ERROR: Unknown control specified.

Before upgrading to Ubuntu 11.10, I never saw any of these issues, so maybe it's related to a kernel upgrade? I'll try the older kernel and see if that fixes the problem.

I'm using a Quickcam Pro 9000

Status changed to 'Confirmed' because the bug affects multiple users.

This stops pan & tilt working for me. I've worked around it by reinstalling logitech.xml as described in this post: http://dickmcjohnnson.blogspot.co.uk/2011/07/logitech-webcam-pro-9000-running-under.html

I was able to make this program work/get past this error by downloading the source and compiling myself. download: http://sourceforge.net/p/libwebcam/wiki/Home/
