I got a Microsoft VX-7000 camera as a gift and tried to get it working. It works fine with luvcview, but not with any other v4l2 sw. I even managed to change the luvcview-code so that it feeds vloopback and I get it working with v4l software (thats ugly but at least makes the camera usable to some extent).
The biggest problem is that the kopete crashes when the uvcvideo module is loaded and the camera is plugged. That is really annoying because the camera can't be plugged on when booting. Is there anything to do or is there some non-standard things in the camera? (That might be possible because it is MS after all). I could debug this more if you could give some hints what to do next? I added some debugging code from older threads and here is the dmesg output: [10750.400000] uvcvideo: Found UVC 1.00 device Microsoft� LifeCam VX-7000 (045e:0723) [10750.400000] uvcvideo: Failed to query (135) UVC control 1 (unit 0) : -32 (exp. 26).
