I am using a video surveillance program (webcamXP), and I would like to use both my integrated webcam (laptop) AND my logitech webcam (C310) as sources; however, it looks like my integrated webcam is not accessible when I plug in the UBS webcam. From the program's perspective, there is only one source which corresponds to whatever webcam is available (integrated webcam when USB is unplugged, and vise versa). I would expect both sources to be available. I'm thinking somehow the computer is seeing the USB webcam and just overriding the integrated webcam. Is there anything I can do to verify this and/or change it to make both available? It's totally possible that it could be the program, but I was unable to find any settings to get it working. I'm running Windows 7.
