When I confronted a similar problem (with a fingertip USB pulse-oximeter) a few years ago, I plugged it in the USB port and then let Windows find the driver. When it did, it configured the USB port as a virtual serial port. With the information Windows provided, I found the manufacturer’s PDF documentation for it that allowed me to write a short MATLAB script to communicate with the device.
I suggest you do the same. There may be only a few manufacturers who produce USB interface chips for such devices, so you may also be able to find ready-to-use MATLAB code that you would only have to modify slightly (if at all) to get it to work with your device.
Of course this applies to Windows, so if you have Linux or an Apple machine, you will have to experiment.
