OpenGD77

Solved! I believed that the radio should be detected as a COM Port to be able to download the Open firmware. With original firmware it was always detected as an USB input device which, however, did not prevent downloading the Open firmware bin. After download it is detected as OpenGD77 (COM3). Thank...

The radio is GD-77 with original firmware and cable. I am trying to download the OpenGD77 firmware radio does not appear as a COM device when it is not in firmware upgrade mode. Running Windows 10 Home.

The cable is not detected as a COM Port.
Tried on different PCs under CPS and separate driver installer.
Do appreciate any suggestion.
