Quickcam Express 046d:0840 Driver versions: v 2.60 from 2.6.31-rc6 and v 2.70 from gspca-c9f3938870ab Problem: Overexposure and horizontal orange lines in cam image. Exposure and gain controls in gqcam and v4l2ucp do not work. By varying the default exposure and gain settings in stv06xx.h, the lines can be orange and/or blue, moving or stationary or a fine grid. Workaround: Using the tool set_cam_exp, any exposure setting removes the visual artefacts and reduces the image brightness for a given set of gain and exposure settings. By default: Aug 21 14:22:02 blackbart kernel: STV06xx: Writing exposure 5000, rowexp 0, srowexp 0 Note what happens when I set the default exposure to 1000: Aug 21 20:44:23 blackbart kernel: STV06xx: Writing exposure 1000, rowexp 0, srowexp 139438350 By the way, is there any possibility of enabling autogain?
