Ports going bad??

I have a brain that ports 1-3 and ports 7-9 are not showing any devices when plugged in… If I switch to ports 4-6 or 10-12 the device shows fine… I have put brain in DFU mode and reinstalled os and firmware and have not seen a difference… right before the ports went to showing nothing it was recognizing motors as bump switches… is my brain bad?

If you plug a known good sensor/motor into port1 and use the VexOS utility do you se anything on port1, or a “?” mark?

I can take a motor showing up on port 6 and plug into ports 1-3 it will not show up at all … no question mark … in the VexOS utility

The communications are setup in quadrants, so 1-3,4-6,7-9,10-12. So it does sound like the controller went bad. Send it to Vex, they will normally replace it.
