When it comes to protocols, USB-C natively supports:
USB 2.0 (480 Mbps)
USB 3.0 (5 Gbps, branded SuperSpeed, now described as USB 3.1 Gen 1)
USB 3.1 Gen 2 (10 Gbps, branded SuperSpeed+, which requires USB-C as a connector type)
DisplayPort (under the ungainly name “DisplayPort Alternate Mode on USB Type-C Connector Standard”)
MHL 3.0 (Mobile High-Definition Link, which you’ve probably never heard of: it’s a way to connect mobile devices to HD displays)
Thunderbolt 3 (on computers that have Thunderbolt 3 controllers, like the new MacBook Pros)
Great article! Worth the read for people like me who have no idea how USB-C works and what it’s capable of. It’s an impressive system.
