All of this is software UX problem. I plug something in that something should tell me what kind of connection it established, is it any good, etc. Try the fast ones opportunistically and tell me when it has to fall back. That's it. If it works I'll know anyway. Even a simple micro-USB on phones needed a pop-up to select what functionality the user wants to activate (charging, file transfer, host mode, debugging). The problem is not new, but most software makers are stubborn miscreants that hate good UX (simplicity, discoverability, accessibility / introspectability, extendability). They usually champion one aspect to the total detriment of the others - eg GNOME3, phone OSes.
