There're two USB modes for the camera. I repeated all tests below in both modes. Look here for a v4l-info output of DV mode: http://tux-style.de/tmp/uvcvideo/dv_mode/v4l-info_dv_mode.txt Looks also like a mess.

Is this a show stopper, even if the camera is working fully?

Sure. I hope your answer could be useful for me. :-) BTW: It seems audio is working with skype. So at least the audio support on the camera works in webcam mode. regards Andreas _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
