Hi I have the same issue. I had it working with a PI camera (used the pi preconfigured install), but it stopped working. I reinstalled the PI.. bought a new pi camera module... but nothing in the drop list.
this is what i get when entering the above commands:
sudo /usr/local/Repetier-Setup/bin/startAllCams<br/>Start from directory /usr/local/Repetier-Setup/bin<br/>Testing active webcams in /dev/v4l/by-path/*<br/>Starting webcam /dev/v4l/by-path/platform-bcm2835-codec-video-index0<br/>Webcam does not support MJPG - using slower YUYV instead!<br/>Best resolution: 0 x 0 at 0<br/>
ps aux | grep mjpg
