I'm trying to use a logitech C920 with reacTIVision on OSX 10.11.6 but after a while of 'starting camera' it says camera disconnected. I have tried modifying the camera.xml file but with no luck.

my available devices are:

no DC1394 cameras found
no PS3Eye cameras found
2 AVFoundation cameras found:
0: FaceTime HD Camera (Built-in)
format: YUYV (2vuy)
1: HD Pro Webcam C920
format: JPEG (dmb1)
format: YUYV (yuvs)
2 MIDI out devices found:
2: to Max 1
3: to Max 2

Any ideas?
