usbc-schem.pngHi,

I am trying to create a PCB that has two (2x) USB-C receptacles and pass the signals end to end. This is my current design:

Mapping

A2->A2,
A3->A3
...
B2->B2
and so on.

As if it is a wire end to end. I know the impedance is 90 ohms, that is not my issue. The USB-C connections works, but with only one orientation of the plug. If I flip the plug, it doesn't work. Any idea on what I am doing wrong?

I really need help.. my head is about to explode...

Don
