Hi, I just bought a HP Elite Autofocus Webcam and it works out of the box on Ubuntu Intrepid Ibex! Now I'm trying to manually control the focus/exposure with no success so far. I believe its the same as with the Quickcam Pro 9000 where one has to dynamically add the controls at runtime. Unfortunately there is no documentation from HP about anything. :( Is there any chance on finding out the correct parameters to add the vendor specific controls? The focus and exposure can be controlled under windows with the software that ships with the camera (ArcSoft Webcam Companion). Furthermore I was able to control the focus through the DirectShow IAMCameraControl interface. Any tips on how to reverse engineer this?
