I have been tinkering with VIM3pro for a while now. Everything was working as I wished. Using 12V USB-PD powersource. Now I recieved Quectel EM06-E LA card, which I installed on M2X board. Next boot and all USB ports were dead. I managed to update Android through USB-C port using PC on the other end. Now everything is still working, but I have no control on system. USB mouse, keyboard or touchpad is not working. I have also tried USB-C hub with USB-PD pass-through, but no luck. Any ideas? Everything seems to be OK physically on the board.
I have been trying to get connection to Vim3 using Ubuntu on laptop. Using ethernet and USB-C no response. Testing connection to 192.168.1.120 gives faulty connection and trying to ping that IP end in loop. I also tested both USB A ports and neither gives no voltage between any pins. I burned latest Android image again with WIN10 desktop through USB-C in maskrom mode and it went as should. Also VIM3 seems to function as should, just no USB. Other observation is that fan is not running at boot as it did before these problems. I have been through checking board on both sides with magnifying glass and powerful light. No obvious damage anywhere.
I probably order new Vim3 and keep this problem solving on background of main project.
