Universal Serial Bus (USB) 2.0 ports are used in conjunction with a number of digital devices, allowing simple connection and widespread compatibility across many computers. However, if you've never used USB technology before, it can be difficult to identify USB 2.0 ports. With so many different input ports on modern computers, USB 2.0 can sometimes be confused for SD media, power input or other niche ports. Luckily, even a novice can identify a USB 2.0 with the proper know-how.

Skill level:


  1. 1

    Look for a small slot on your computer measuring about 1cm wide. Above or next to this slot should be a logo that looks like an elongated arrow with two smaller lines protruding out of each side, almost like a pitchfork. The left-hand protrusion will have a small circle on its tip; the right-hand protrusion will contain a square. If you notice this slot and associated symbol, your computer has a USB port. However, you need to do some further investigating to learn whether your computer is using a USB 2.0 port or an older USB 1.0 or 1.1 model.

    Look at your computer's case for a manufacturer's label. If your computer was made after 2002, the ports on your PC are most likely USB 2.0 ports, according to Microsoft. If you cannot find a label, you can look in the computer's Control Panel to determine whether the port is 2.0 capable or not.

  3. 3

    Turn on your computer. Click on the "Start Menu" and open the "Control Panel."

  4. 4

    Click on "System and Maintenance," at the top left-hand corner of the Control Panel window.

  5. 5

    Click on "System," then "Device Manager." A new window listing all internal and external devices currently installed on your computer will open.

  6. 6

    Scroll the Device Manager listings until you find "Universal Serial Bus Controllers." Click on this option to expand a list of all USB controllers on your computer.

  7. 7

    Browse the list of USB controllers and look for at least one controller that includes the words "enhanced." According to Microsoft, if your computer features "enhanced" USB controllers, then your USB ports are 2.0 compatible. If you do not notice any USB ports featuring this key term, then your ports are older 1.0 or 1.1 models.
