Rands (Michael Lopp) has put together a great guide of mess that USB-C has created. This is probably a good one to bookmark for future reference: The Lie: Every USB-C cable and port looks identical, so they must all do the same thing. Except a USB-C port running USB 2 and a USB-C port running Thunderbolt 5 differ by 250×. The Truth: USB-C is a connector shape — the small oval that plugs in either way. (USB-A is the rectangle you have to flip three times.) The protocol running through it (USB 2, USB 3, USB4, Thunderbolt) determines speed, display, and power.
