Comment 4 for bug 811604

Happens to me since I updated my ubuntu 11.04 a couple days ago. It filled 800GB of logs.
I had to kill it:

sudo killall -9 uvcdynctrl

it was repeating the message a zillion times:
[libwebcam] Warning: The driver behind device video0 has a slightly buggy implementation
  of the V4L2_CTRL_FLAG_NEXT_CTRL flag. It does not return the next higher
  control ID if a control query fails. A workaround has been enabled.

What even starts uvcdynctrl? Does it happen when I plug in the camera? When something opens the driver?

$ uvcdynctrl --version
