Cube Orange not connecting to the QGC

Hello, I have seen this problem on another post but they have solved it by downloading some version of the mission planner. But I have the mission planer on the pc so that didn’t solve the problem.
But the same setup gets recognized by other laptops. This specific laptop can not connect to the controller.

Can you try uninstall ,re-install MP and re-install firmware after?
What firmware did you use before on this unit ?
Is there any disconnection during firmware upgrade?
Best regards,

Hi, I solved it. After re-installing the MP it worked fine.
