3DR Radio 433MHz Module no COM Port assignment.



New here and ran into a issue with the ground station module. All worked fine, connection to COM7 anytime I pluged it in. But now the radios connect (solid green light) but my laptop refuses to assign a COM port to the module.. just powers it up but no Port. Same happens if I use the "Air" Module as ground module.. I have no idea where to look else. Did hardware scans.. everything.. broken?? But how can both units be bad?

Direct USB still works fine.. just the telemetry modul refuses to load the driver to assign a COM port.


Thank you for all advice in advance.

  • Solved... should be a broken wire inside the USB cable I got from 3DR
