My cube black didn’t work today.
I can’t connect it using USB by mission planner.
The port number was lost.
It worked before as com8 , when I plug in, sometime shows com8, sometime shows com3, but both one doesn’t connect.
Joystick remote control and telemetry control was lost too. GPS light is not normal.
What is wrong.
How to repair it.
Thank you for any advise.
