Thank you for your reply, Scroller! I used usbview to check for the kind of connection to the camera: 480 MBit/s (HighSpeed). The bus the cam is using is not used by anything else... Sometimes it completly locks up an gstreamer, which is used by cheese, sends its test-picture... There NO technical specifications in the booklet of the cam. I wonder why... What's about the pictire quality of the Playstation "Eye" Cam, Scroller? Ok? Good? Better? Best??? ;))) Meino -- Please don't send me any Word- or Powerpoint-Attachments unless it's absolutely neccessary. - Send simply Text.
