Please help ma find out part of pixhawk 2.4.8

Hi all! I recently ran into a problem that my pixhawk 2.4.8 won’t connect to my computer. I was able to find out that there are some components on the board that are faulty, but I cannot identify one of them. Component markings on my V240 07 01 X802 board. I have seen photographs of boards where this part has a different marking - V240 06 03 X923. Please tell me what kind of detail this is? Maybe someone has encountered such a problem
