How do I use videoinput function while connecting to IMPREX frame grabber

I cannot connect to VCE EXPRESS frame grabber http://www.imperx.com/frame-grabbers/vce-express in Matlab and was wondering if you have experienced similar problem and can help.

First, I can use AMCap or VCE Express application to view the video and that works okay, so that tells me that the driver installation and hardware setup is working.

In Matlab, I can use imaqhwinfo('winvideo') to get a list of available devices and I get the following for VCE_EXPRESS: DefaultFormat: 'RGB32_0x0' DeviceFileSupported: 0 DeviceName: 'VCE-Express Capture' DeviceID: 3 ObjectConstructor: 'videoinput('winvideo', 3)' SupportedFormats: {'RGB32_0x0'}

As you can see the SupportedFormats appear to be RGB32_0x0. I am not sure why it is 0x0 and why no other formats are supported. Now if I try to connect to the grabber using: videoinput('winvideo',3)

It comes back with an error that width and height have to be greater than 0, which is referring back to the supported formats that were returned earlier. An insight into it would be appreciated.
