We used a LifeCam HD-3000 (connected to a roboRio USB port) for a few weeks, and then seemingly out of nowhere, the roboRio was no longer able to connect to (get images from) the LifeCam. We replaced it with a new LifeCam, and it worked again for a while.

This whole sequence repeated itself three times, with three LifeCams. All the LifeCams can still be used from a PC, so we're pretty certain that we weren't just damaging our LifeCams.

Has anyone else had this problem? Any idea how to fix it? Thanks for any help.

Extra info: after a LifeCam stops being able to connect, the little blue light on the LifeCam turns on momentarily at startup and then goes off. The normal, working behavior is that the light remains on whenever the robot is on.

We are using an OpenCV VideoCapture (in Java) to connect to the camera.
