Some old code that I have been using for a serial RS232 com port device works well. This device through a RS232-USB convertor works well too - that is, the code is looking for a COM port number and the reading of the serial input is correct.
The new version of this serial device is a USB only unit and I dont see a "COM PORT" in the system hardware configuration? how do I "see" my new USB device and let my code be reused? Or do I need to treat the USB differently?
