I have an installation that uses a Logitech 920 camera to record and display video. The camera is hanging at the end of a 15 foot powered USB extension. After restarting the MacMini and launching my application, the feed from the webcam runs at only 1-2fps. Relaunching the app does not fix the issue, but power-cycling the camera (unplugging then plugging in) does.
When I open PhotoBooth, the frame-rate is always good, even when my application is running at the same time with 1-2fps.
Has anyone seen anything like this? Is there a way to power-cycle the camera from software?
