Multiple USB 6501 Devices

I'm a student and working with NIDAQmx for the first time for my small project. I am developing an application in VB.NET to initialize an RFSwitch which is a USB6501 device. Currently my program can initialize a USB 6501 device if one is connected to the PC. 

I wish to improve my program so that on startup it can detect if more than one USB 6501 devices are connected to the PC so that I have the option of which device to initialize by selecting it from a run time generated dropdown list may be. Is there anyfunction through which I can detect all the devices of a particular kind connected to the PC and also access them to initialize any one of them.

Please help me! I tried to figure this out alot and read many forums also but couldn't do it. As part of B.Tech project, this is very urgent.

Thank you.
