VCC and GND are shorted together with TRS

[joric]

Despite all keyboards use duplex serial now, A.Dux still can't use TRS cables. I suggest reorder TRRS pins similar to Corne. See https://github.com/joric/jorne/wiki#trrs.

Upd. Checked TRRS footrpint with mutimeter, two common pins at the bottom essentially short together Sleeve and Tip.

This is the Ergogen issue, since A.Dux was made in Ergogen, see autogenerated A.Dux PCB here: https://ergogen.cache.works.
Looks like TRRS footprint is bad, shorting two bottom pins is essentially the same as shorting Sleeve and Tip then TRS shorts Sleeve and Ring2 and we only get 2 nets instead of 3.

If we use "symmetric: false" to untie Sleeve and Tip, the footprint will be too big.

I guess it's easier to leave it as is and just use TRRS cables.
