In Windows, how do I tell what version of USB ports I have installed on my computer?

Many computer manufacturers do not clearly mark USB port versions. Use the Device Manager to determine if your computer has USB 1.1, 2.0, or 3.0 ports:

  1. Open the Device Manager.

  2. In the Device Manager window, click the + (plus sign) next to Universal Serial Bus controllers. You will see a list of the USB ports installed on your computer.

    • If your USB port name contains "Universal Host", your port is version 1.1.
    • If the port name contains both "Universal Host" and "Enhanced Host", your port is version 2.0.
    • If the port name contains "USB 3.0", your port is version 3.0.
