VideoCapture open() won't open second camera

I am trying to use stereo cameras. I have two logitech c525s. The first camera opens fine and displays images but when I use the VideoCapture.open() command to open the second camera, the program hangs. I can access each camera individually.

I am using Windows 7, Visual Studio 2010 and C++ Windows device manager sees both cameras individually.

Is there something I am missing or neglecting to do?
