If the radio is connected while it is on, the drivers for this USB circuitry will not load. Without the drivers loaded, there will be no communication between the radio and the computer for any program. Checking in Device Manager, there will be no listing for the radio under Ports - Com and Lpt.

Turn the radio off, count to 10, turn the radio back on. The power on sequence will trigger New Hard Ware found and driver installation.
