If anyone of you has problems with your pcb disconnecting, apparently reflowing and soldering a bit extra on the 5 usb port solderjoints fixes these issues. Brendan told us that on the kb-kustoms channel and it so far worked for keyboarduser4 and me, who both had problems with it.
These five guys below. I also added kapton tape around the usb port to isolate it, the reflowing and soldering is probably what fixed it though.
