Your USB-C port might be running at USB 2.0 speeds — here’s how to check
USB-C is fast. Well, that’s not entirely true. USB-C is an oval-shaped connector that we associate with much faster transfer speeds and charging for our devices. But that’s all USB-C is: a standard that defines the connector shape we all love. It replaced a generation of slower, uglier ports, and we all collectively decided it meant things got better. Except sometimes it didn’t. Sometimes your USB-C port is running at USB 2.0 speeds, and it never really lets you know unless you spend time figuring out the problem.

Why your USB-C port isn’t as fast as it should be Capped, but you don’t know why Standard Defines Does NOT define USB-C Connector shape and pin layout Transfer speed, data protocol, or power delivery level USB 3.2 Transfer speed (up to 20Gbps) Connector shape — works with USB-A, USB-C, or internal USB 4 Transfer speed (up to 40Gbps) and protocol Connector shape — but requires USB-C Thunderbolt 4 Speed, protocol, and minimum port requirements Connector shape …
