You will likely only encounter this port in an old computer, if at all.

It supports much lower transfer speed of 1.5 Mbps, or 12 Mbps at full bandwidth. The white color in USB port indicates it is USB 1.X, which is some of the very early standards. If you’re wondering why that’s the case check out my previous post:- Why motherboards & laptops still come with USB 2.0 ports When USB 3.0 Is Backward Compatible? This port still comes in motherboards nowadays, and is still useful for many things. You can connect multiple devices to one of these ports using a hub with little to no problems.
This is the ideal port to connect devices that don’t require high transfer speeds, like keyboards or mice. Since it’s an older standard, it supports slower transfer speed up to 480 Mbits. Many high-end motherboards come with multiple USB 3.2 ports:-īlack USB port indicates that the port is USB 2.0. This is the fastest speed USB ports have reached at the time of me writing this article (although the upcoming USB 4.0 will support double that speed:- and up 40 Gbit/s). This version supports an even faster transfer speed up to 20 Gbit/s. When a USB port is red, it indicates the port is USB 3.2. Again, assuming your device actually support these speeds. Since these ports are fast, they can be ideal for connecting a dock or devices that requires a lot of transfer speed. These ports support transfer speed up to 10 Gbit/s. Similar to how USB 3.0 ports are blue, USB 3.1 come in Teal Blue (like the one in the picture). These ports support speed up to 5 Gbit/s, device and cable need to support this speed to benefit from it. Even the cables for that standard are blue.
This is the conventional color for USB 3.0 port, and one of the main ways to distinguish it from the other ports. Sometimes, Color Enough Is Not Enough To Figure Out The Port Version.
