That appears to be kind of the point of USB-C-- identical-looking ports which may or may not actually do the same thing. A given USB-C port might be a host port; might be a device port; might be capable of serving in both roles; might support video (over HDMI or DP or some combination of the two) or might not; might support Thunderbolt or might not; might support high-voltage/high-current power delivery or might not... and all on the same connector, so good luck trying to figure out what supports what without looking at manuals.


I see it as one of the big failings of USB standards in recent years.

USB used to be simple, and they worked so hard to make it so that whatever plug could be plugged into whatever compatible socket.

Then we had USB on-the-go, and issues with then a micro-A port isn't just a micro-A port.

And now we have USB-C and Thunderbolt. Ugh.


Same problem applies to USB-C cables. Understandable why (want to spend $100 for every cable you buy?) but intensely frustrating.
