Hi, I have two Pixhawk Cube Orange Plus boards. One of them can connect to PC and works properly while the other one is not seen as an USB device by the computer. In Mission Planner, the board can not be detected. In Device Manager, there is no com port for the board (there is no beep when I plug the board). I uninstalled and reinstall Mission Planner and all drivers. I tried to install older versions of Mission Planner. There is still no response. I also tried to connect it to computer with the USB port (pins) but it does not work. The board gets power (led lighting). What could be the reason? Thanks in advance.
