I detected some things on this connector which were a bit questionable.
VSS had a small contact on the right side of P2 with VSS line.
I don't expect that this was inteded, as it would mix GND line (which is the Wire Shielding, grounded by the PC) with the internal grounding potential VSS. Am I right on this?
Re-routed GND Line

Next is the routing at the RX1 and TX1 pads.
Initially RX1 and TX1 were wired like displayed on the picture below.
Which means RX1 is constant +5V and TX1 is constant VSS.

I re-routed that like displayed below. Would this change be correct or did I miss some detail that would explain the deciscion with RX1 == +5V and TX1 == VSS?
