Yeah so that's the symptom of no power to the unit. While USB powers the controller, there's no data from the motors. Make sure the DC plug is all the way in and e-stop switch is de-pressed.
Putting some superglue on the DC connector shell from 3 sides and inserting it back into the plastic shell will do the trick (apologies due to QC mistake) .
