Identify The Types Of USB Ports On Your Computer with 3 basic Steps


USB ports are widely used to connect devices and transfer digital data. It is important to understand the different types of USB ports available on your computer. In this article, we will explore the various types of USB ports, their functionalities, and how you can identify them on your computer.

Step 1: Know the Types of USB Ports on Your Computer

Sort by Connector Shape

USB ports can be categorized based on their connector shape. The two most common types are:

  • USB Type-A: This rectangular-shaped connector, measuring about 1.4 cm (9/16 inch) in length and 0.65 cm (1/4 inch) in height, is the most popular USB port. It is commonly used for wired mice and keyboards.

  • USB Type-C: These smaller-sized ports are typically found in slimmer laptops like the latest MacBooks and Dell XPS series. The highlight of this port is its reversible design, allowing for easy plugging into the device.

Other USB standards, such as Micro USB, are commonly used in mobile devices like smartphones and tablets, rather than computers. Additionally, micro USB ports can be found in some older devices like digital cameras and computer peripherals. However, micro USB ports have been largely replaced by micro-USB and USB-C cables.

Sort by Transmission Speed

USB technology has evolved over the years, offering different versions with varying transfer speeds. Here are the current USB port types and their transfer rates:

  • USB 1.0 (1996): 1.5 Megabits/second (Mbps)
  • USB 1.1 (1998): 12 Mbps
  • USB 2.0 (2001): 480 Mbps
  • USB 3.0 (2008): 4.8 Gigabits/second (Gbps)
  • USB 3.1 (2013): 10 Gbps
  • USB 3.2 (2017): 20 Gbps
  • USB 4.0 (2019): 40 Gbps

USB 2.0 ports support uni-directional data transfer, meaning they can either send or receive data, but not both simultaneously. USB 3.0 introduced simultaneous sending and receiving capabilities. Additionally, newer USB versions can deliver more power to connected devices. For example, USB 3.0 can provide up to 900mA, while Type-C USB connectors can support up to 100 watts of power.

Step 2: Check the USB Ports on Your Computer

Manufacturers often label the USB ports on computers to indicate their type. Look for labels such as 1.0, 1.1, 2.0, 3.0, or 3.1 on your computer’s ports. Furthermore, USB ports are now color-coded, making it easier to identify their types. Refer to the table below to understand the meaning of each color:

Check the USB Ports by Color

Another method to identify the USB ports on your computer is to check for symbols next to the ports. The symbols correspond to different port types. See the table below for reference:

Check the USB Ports by Symbol

Using the color and symbol references, you can easily identify the types of USB ports on your computer.

Step 3: Identify USB Ports by Motherboard’s Technical Specifications

For Windows

If you are using a Windows device, you can determine the USB port types by following these steps:

  1. Press the Windows Key + “R” to open the Run Command dialog.
  2. Type in ‘msinfo32’ and press Enter.
  3. Find the value under “System Model” and search for the specifications list of your laptop or motherboard on the manufacturer’s website for accurate results. Look for terms like USB, USB Type-C, and similar terms.

For MacOS

MacOS users can identify their Mac model by clicking the Apple logo and selecting “About this Mac.” This will display an overview of the device, including the model name. Visit the Apple support website for notebooks and desktops to check the technical specifications corresponding to your model.


Understanding the different types of USB ports on your computer is crucial for selecting the right USB cable and optimizing data transfer speeds. It also helps avoid potential compatibility issues. By following the steps outlined in this article, you can easily identify the types of USB ports on your computer and make informed decisions when connecting devices.
