Cam Socialize HD VF0610", Device ID: 041e:4080, Driver: uvcvideo is running perfectly on Fedora 16 Linux, except one thing: When I try to switch on "White Balance Temperature, Auto" or just try to change "White Balance Temperature" slider I get a failure message and it won't work. All other controls, like contrast, gamma, etc. are working. "v4l2-ctl -d 1 --set-ctrl=white_balance_temperature_auto=1" produces an error message: "VIDIOC_S_CTRL: failed: Input/output error white_balance_temperature_auto: Input/output error" As soon as I boot Windows (inside Linux out of a Virtual Box), start the camera there and go back to Linux, I am able to adjust and switch on the White Balance things in Linux. "v4l2-ctl -d 1 --set-ctrl=white_balance_temperature_auto=1" working fine after running the camera in Windows. Everytime I switch off my computer or disconnect the camera, I have to run the camera in Windows again, bevor I can adjust White Balance in Linux. What can I do to get White Balance controls working in Linux, without having to run the camera in Windows every time? Is there a special command I have to send to the camera for initializing or so? Best regards Aurel
