@twix @mwichary @drahardja @atomicbird @Drwave nope, not working on anything like that. you could possibly detect e-markers and check connectivity of some pins (SBU1/2, D+/- but only in one orientation, SSTX/RX) I think. if you get code execution on the type-c port controller you could maybe do some more tests. would be a fun project but nothing I'm personally going to spend time on.
