Connect Microsoft Lifecam to Matlab

I am having trouble using the Microsoft Lifecam with Matlab. I have already installed all the drivers (including the USB webcams Package in Matlab) and the camera seems to work fine when I open it from its own app. However, when I open it from Matlab I get an error and I need to close Matlab.

This is the way I am doing it:

cam_List = webcamlist;     which returns the name of my laptop's camera and the Microsoft camera

cam  = webcam(2);      (with the laptop's camera [webcam(1)] works fine)

The error I get is shown on the image

Any help is much appreciated.

Thanks in advance

This is everything I can find for Microsoft Hardware Support. See if your camera is listed.
