Do you see a list of cameras if you run imaqtool?

What *does* show up in the "hardware browser" in imaqtool? Anything at all? I'd be surprised if your camera weren't there, but that's what you're insisting is the case. If it's not there then MATLAB won't see it, and Windows (or your operating system) likely doesn't see it either. Are you using Windows? If you are, run Device Manager and open the Imaging Devices category. Does it show up there? If not then Windows doesn't even see it.

Why? It was four and a half years ago. I'm sure he is not still waiting for help.

I thought he might need the following link on "webcam" or "Integrated cam":
