How To Find Out What Usb Port Is Being Used?

The Universal Serial Bus (USB) is an essential tool in today’s world of technology. From data transfer to powering devices, USBs have become the ultimate solution. However, identifying which USB port is being used can be a confusing task, especially when multiple ports are available on a computer. Luckily, there are several ways to determine which port a device is connected to.

Firstly, it’s crucial to differentiate each port on a computer. Some may be located on the front panel, while others may be found at the back. Additionally, there may be USB 2.0 or USB 3.0 ports, which may require different methods of detection. Knowing where each port is located and whether they are 2.0 or 3.0 can make finding out which USB port is being used easier. In the following paragraphs, we will explore some of the ways to detect which USB port is being used, regardless of its location.

How to Find Out What USB Port is Being Used?

To find out which USB port is being used, you can follow these steps:

1. Check the physical location of the USB port: Look at the USB ports on your device and try to identify which one your USB device is connected to.

2. Use the device manager: Open the Device Manager on your computer (by typing “Device Manager” in the search bar or by going to Control Panel > Hardware and Sound > Device Manager). Look for the Universal Serial Bus controllers category and expand it. You should be able to see a list of all the USB ports on your system.

3. Use third-party software: There are various third-party software tools available online that can provide you with detailed information about the USB devices connected to your computer and the ports they are connected to. Some popular options include USBDeview, USBView, and USBlyzer.

4. Use the command prompt: Open the command prompt on your computer (by typing “cmd” in the search bar or by pressing Windows key + R and then typing “cmd” in the Run dialog box) and type “wmic path Win32_USBControllerDevice get Antecedent, Dependent”. This should provide you with a list of all the USB devices connected to your computer and the ports they are connected to.


1. How can I determine which USB port is currently in use on my computer?

Answer: On Windows, open the Device Manager and navigate to the Universal Serial Bus controllers section. Look for the device that is currently connected, and its corresponding port will be indicated in the properties window. On Mac, open the Apple menu, click on About this Mac, and select the System Report. Under the Hardware section, click on USB to see the list of connected devices and their corresponding port numbers.

2. Is there a way to identify which USB port is most suitable for charging my device?

Answer: Typically, USB ports with higher amperage outputs are better suited for charging. On most computers, USB 3.0 ports are designated with blue color, indicating they have higher power output. You can also check the USB port’s specifications to determine its power output.

3. Can I use a USB hub and still identify which port my device is connected to?

Answer: Yes, you can. When using a USB hub, the connected devices will be listed under the appropriate hub listing in the Device Manager or System Report.

4. What should I do if the USB port I need to use is not functioning?

Answer: First, try restarting your computer and checking if the port is recognized. If it still is not functioning, you may need to update the driver software for the port or contact a technician for further assistance.

5. How can I troubleshoot a USB device that is not detected by any of my ports?

Answer: First, ensure that the device is functioning properly by testing it on another computer or device. If it still is not detected, try a different USB cable or port. If none of these solutions work, the issue may be with the device’s drivers or firmware, and you may need to contact the manufacturer for further assistance.


In summary, there are several ways to find out which USB port is being used. You can use the Device Manager in Windows, check the system profiler on a Mac, or utilize dedicated third-party software. Knowing which port is being used can come in handy when troubleshooting connectivity issues or optimizing device performance. With the above methods, identifying the specific USB port being used on your computer should be a breeze.
