Autobrightness does not work on two USB cameras

Question

In my Kmotion server I have 2 USB camera's. On startup I can see some color-setting changing but the brighness is not adjusted. In /etc/motion/motion.conf the setting "auto_brightness on" and i tried several values for "brightness". Both camera's seem to stay in fixed sensitivity. In the logfile /home/robbert./kmotion/www/motion_out the parameter ("Brightness", default 72, current 72) does not react on any brightness parameter in de motion.conf file nor if I physically cover this camera from light.

The quickcam pro is that sensible it only shows a white screen in daylight;-(

I cannot find errors in /var/log/dmesg with the cameras.
