motion_init: Error capturing first image

Question

Hi,

I have a Philips SPC220NC USB webcam. The kernel driver is pac207. I can grab pictures from the camera e.g. with vgrabbj, but motion returns a "Error capturing first image". I don't know if the "v4l2_select_input: Device doesn't support VIDIOC_G_STD" has any meaning for my problem. Thank you for your help!
