Hi,
I have an A1278 820-3115-B, that works well, but that the USB ports doesn't work, and I don't know where to start.
Testing them with the Chipmunk USB Tester , on one port I don't have any activity (light). On the other one, it seams to have activity, but have no 5V light. The 5V power rails seams to be ok.
Can you help? Where should I start?
