Your question is not clear. Are you referring to talking between two computers via USB, or between a computer and some instrument? If it's between two computers I would not recommend USB, as TCP is far easier and faster. If it's with an instrument, then it depends on the instrument and what drivers you have. You would need to know if the instruments requires RAW communication or whether it conforms to the Test and Instrument Class. You can read more here: http://zone.ni.com/devzone/cda/tut/p/id/4478.

The USB interface on the pcb has to be implemented by something. Do you have a microcontroller, or something like that? If you don't know much about USB communication, then this will be very difficult for you. In addition to the KB article I mentioned before, it would be worth your time to read this nugget: http://forums.ni.com/ni/board/message?board.id=170&thread.id=340676.

If you haven't implemented anything yet in hardware, you may want to consider chips like those sold by FTDI which can provide a virtual COM (serial) port interface for applications via their drivers.
