USB 3.1 Ports Only Working as USB 2.0 - Troubleshooting Guide

If you have recently upgraded your computer or purchased a new one, you might be excited to take advantage of the faster transfer speeds offered by USB 3.1 ports. However, sometimes these ports may not work as expected and only operate at USB 2.0 speeds. This can be frustrating, but don't worry. In this troubleshooting guide, we will walk you through some common causes and solutions for this problem.

Check for USB 3.1 Compatibility

The first step is to ensure that your computer or device actually supports USB 3.1. Check the specifications of your computer or consult the user manual to confirm this. If your computer does not have USB 3.1 ports, it is not possible to achieve USB 3.1 speeds.

Update USB Drivers

Outdated or incompatible USB drivers can cause USB 3.1 ports to function as USB 2.0. To update your USB drivers, follow these steps:

1. Open the Device Manager by pressing the Windows key + X and selecting "Device Manager" from the menu.
2. Expand the "Universal Serial Bus controllers" section.
3. Right-click on each USB controller and select "Update driver."
4. Choose the option to search automatically for updated driver software.
5. Wait for the process to complete and then restart your computer.

Disable USB Selective Suspend

USB Selective Suspend is a feature that allows the operating system to conserve power by putting USB devices into a low-power state when they are not in use. However, this feature can sometimes interfere with the proper functioning of USB 3.1 ports. To disable USB Selective Suspend, follow these steps:

1. Open the Power Options by pressing the Windows key + X and selecting "Power Options" from the menu.
2. Click on "Change plan settings" next to your selected power plan.
3. Click on "Change advanced power settings."
4. Expand the "USB settings" section.
5. Set both "USB selective suspend setting" options to "Disabled."
6. Click "Apply" and then "OK."

Check USB Cable and Device

It is possible that the USB cable or device you are using is not compatible with USB 3.1 or is faulty. To troubleshoot this, try the following:

• Try a different USB cable: Use a known working USB 3.1 cable to connect your device to the USB 3.1 port. If the problem is resolved, the original cable may be faulty.
• Try a different USB device: Connect a different USB 3.1 device to the port. If it works properly, the original device may not be compatible with USB 3.1.
• Test the USB 3.1 device on another computer: Connect the USB 3.1 device to another computer with USB 3.1 ports to see if it works. If it does, the issue may be with your computer.

Reset BIOS Settings

In some cases, incorrect BIOS settings can cause USB 3.1 ports to function as USB 2.0. To reset the BIOS settings, follow these steps:

1. Restart your computer and enter the BIOS setup by pressing the designated key (usually Del, F2, or F10) during the startup process.
2. Navigate to the "Advanced" or "Advanced Settings" section.
3. Look for an option related to USB or USB ports.
4. Reset the USB settings to their default values.
5. Save the changes and exit the BIOS setup.

Consult Manufacturer Support

If none of the above solutions work, it is recommended to contact the manufacturer's support for further assistance. They may have specific troubleshooting steps or firmware updates available to resolve the issue.

By following these troubleshooting steps, you should be able to resolve the issue of USB 3.1 ports only working as USB 2.0. Enjoy the faster transfer speeds and improved performance that USB 3.1 has to offer!
