I'm making Rover.
But I think there's a problem with the ardupilot mega 2560 board.
When you connect the USB, the green LED and the red LED are fixed and the blue LEDs are turned off.
Device Manager " Unknown USB Device (Device descriptor request failed ")
There is no " com X " in mission planner.
and sometimes [green - fix], [red - fix], [blue - blink]
Please let me know if there is any solution.

What is an "ardupilot mega 2560 board"? Do you have a link?
Ah, that's the old APM board. I'm not familiar with that website (I think it's an old one no longer maintained), but that board has not been produced or supported for years. Where did you get it?
It's possible to use old APM boards, but you have to use older versions of the APM code prior to 2015. Not recommended.
