Recently purchased two Cube Orange + with ADS-B carrier boards. I’m having trouble with both buzzer/USB extension cables (plugged into the 6 pin USB port). The buzzers are working fine, whether powered from the flight battery or through the integrated USB port. But the external USB ports are dead as a door nail and won’t fire up the Autopilot. This happens with both Autopilots and with both extension cables. Laptop is powered by mains (i.e. not just relying on battery). Any thoughts? Thanks v much.
