Does the driver for your device have C/C++ functions that you could call to control it? If so, write a simple DLL in Visual Studio which uses the standard MEX interface with Matlab, and call those C/C++ functions there. Build the DLL and rename it from .dll to .mexw32 (or .mexw64, if you're using a 64-bit Matlab). Then you should be able to run it by calling the filename as a function from Matlab.
Without knowing more about your device, I can only give examples of controlling other USB devices. For example, you could use the C code from this article to unmount a USB flash drive; just compile the code into a DLL and call it from Matlab.
