What sort of USB device? Keyboard, mouse, camera, USBTMC instrument, daq device, etc.?

Okay you probably mean a USB thumb drive.  If this is the case run the List Folder function under File I/O >> Advanced.  Provide a blank path to the input and it will return the disk drives on your machine as an array.  You can then see if there is a E drive or whatever which is your drive you plugged in.  Or look for some files on the E drive that you expect to be there.  Or there are other functions for finding the lable, volume and serial number of the drive which can also be used to identify it.

But if you are talking about any USB device checkout DevCon.  Here are a few links
