Hello,

The USB port cannot be used as easily as for example the serial or parallel port because it does not have a fixed protocol like the serial port. All devices that are connected to the USB port work with some driver (usually some kind of dll) which you have to port to LabVIEW. So call the driver dll's from LabVIEW to send or read commands from and to your USB port.
