It is possible that you have ever connected a device to your computer and noticed that the transfer speed is not expected, or that certain devices work better in some ports than in others. This is because not all USB are the same, and differentiating between them can help you optimize time and avoid unnecessary frustrations. But how is it made? The answer is much simpler than it seems: you just have to look at color. For example, USB 3.0 ports usually have an internal blue connector, while USB 2.0 use black or white connectors.

Specifically, it belongs to USB 1.0 and 1.1, which offer very limited transfer speeds. The devices connected to these ports can reach a maximum of 1.5 mbit/s (188 kb/s) in its most basic version and up to 12 mbit/s (1.5 mb/s) in its improved version. Due to its low speed, these ports were mainly used for keyboards, mice and web cameras in old equipment. Internal black connector on the other hand, the black color indicates that we are facing a USB 2.0 port, a more modern version that allows a transfer speed up to 480 mbit/s (60 mb/s).

These ports provide greater power by an increase in amperage without altering the voltage. In many cases, they are labeled as ‘Always On’, which means that they continue to supply energy even when the computer is off. Although they can be USB 2.0 or 3.x, their main function is to optimize the load of electronic devices.
