Hi Laurent, I'm running luvcview with text output - brightness and other parameters are within bounds and acknowledged to be set correctly by the driver, but preview image doesn't change. Regards, Paul Jurczak

I'll add the device to the website (after solving your problem of course :-)). > Driver accepts requests to change brightness, contrast, saturation etc., > but the image is not affected - camera seems to be stuck on automatic mode. > Here is the dump from UVCView (I've omitted the audio part): Brightness seems to be supported by the device. There is no automatic brightness mode in UVC. Make sure the value you are trying to set are within the supported range. You can retrieve the minimum, maximum and step values using VIDIOC_QUERYCTRL. If the values are not out of bounds, please enable control debugging (with the trace module parameter) and have a look at the kernel log for possible clues.
