Four green strokes in the previous photo - these are the same A11-A10 and B11-B10 after the multiplexers (the most delicate and unprotected parts of the port - they damaged first)

There are no separation capacitors, as you can see (due to the required wire length).

If they get a supply voltage or a signal from the USB2.0 part - they burn out and stop diod calling mirrorily.

As far as I know, the damage is irreversible and occurs in the main chip on the board (repair is not advisable).
