Confusion in USB naming conventions

USB names have been pretty confusing, with USB 3.0 changing to USB 3.1 Gen 1 and then to USB 3.2 Gen 1×1. Thankfully, they’re trying to simplify things by focusing on speed ratings, which should make it easier to understand as we move forward.

Other USB port colors and meanings

Besides black, blue, and red, you might see yellow or green USB ports. Yellow usually means the port keeps powering devices when your computer is off, and green might be a special thing for some brands without a standard meaning.

Summing things up

Red USB ports are typically about USB 3.2, offering way faster data transfer compared to older versions. They might also mean the port can charge devices quicker or even when your computer is off or asleep. But, colors aren’t always a sure thing, so always double-check your device’s manual or use software tools to get the real scoop.
