USB ports are a vital component of any computer. They allow you to connect peripherals like printers, external hard drives, webcams, and more. However, we’ve all experienced the frustration of plugging in a device only to have the computer not recognize it. The USB port lights up, but nothing happens.
Don’t despair. There are several techniques you can try to diagnose and resolve USB port problems on your computer. In this guide, we’ll walk through the common issues and solutions, using examples from Australian tech support business GPK to illustrate.
Why Might USB Ports Stop Working?
There are a few potential culprits when USB ports don’t seem to recognize devices:
- Faulty USB cable: The cable connecting your device could be damaged or worn out. Try swapping to a different cable.
- Outdated drivers: Your USB drivers may need updating to work with newer devices and operating systems.
- Power supply issues: Insufficient power to the USB port can prevent device detection.
- Physical damage: The USB port itself could be dirty, broken or bent.
- Software conflicts: Some programs can interrupt communication between devices and USB ports.
Follow these tips from onsite IT support experienced techs to troubleshoot and fix your computer’s USB issues.
Check Physical Damage
Carefully inspect the problematic USB port for any obvious damage. Are the metal contacts clean? Do they appear scratched or bent? Is the plastic housing cracked? Damage to the port can prevent a solid connection.
Try plugging the device into another USB port as a test. If it works fine there, the original port is likely faulty and needs repair.
Update Drivers
Out-of-date drivers are a common source of USB conflicts. Simply updating to the latest USB drivers from your device manufacturer may get things working again.
Here’s how to update drivers in Windows 10:
- Open Device Manager
- Expand the Universal Serial Bus controllers section
- Right-click on the USB device and select Update driver
- Click Search automatically for updated driver software
- Restart your computer after the update completes
Be sure to install drivers from the device maker rather than using Microsoft’s generic drivers. Contact GPK if you need assistance finding the correct drivers.
Change Power Settings
Some external hard drives and other high-power USB devices need extra power to run properly. If they’re not getting sufficient current from the USB port, they won’t be detected.
Changing your computer’s USB suspend settings can help provide consistent power to your USB device. Here’s how to adjust this in Windows 10:
- Go to Control Panel > Hardware and Sound > Power Options
- Click Change plan settings on your current power plan
- Select Change Advanced Power settings
- Expand the USB settings section
- Change the USB selective suspend setting to Disabled
Disable ‘USB selective suspend’ to keep USB ports powered on. Contact GPK support if you continue having power issues.
Uninstall USB Controllers
As a last resort, you can uninstall the USB controller drivers to force a fresh install. This can clear any software issues causing detection problems.
- In Device Manager, expand Universal Serial Bus controllers
- Right-click on each USB device and select Uninstall device
- Restart your computer and Windows will auto-reinstall the USB controllers
- Reconnect your USB device and see if it’s recognized properly again
GPK techs recommend re-installing controllers one by one, and restarting after each, to isolate any conflicts.

Frequently Asked Questions (FAQs)
Why did my USB port suddenly stop working?
There are a few common reasons USB ports can suddenly stop recognizing devices. Faulty cables, outdated drivers, power supply issues, physical damage to the port, and software conflicts can all cause USB connectivity problems.
How can I tell if my USB port is physically damaged?
Carefully inspect the USB port for any signs of physical damage. Look for scratched/bent metal contacts, cracked plastic housing, missing pins, or loose ports. If another USB port works fine, it indicates a problem with the specific faulty port.
Why do my USB devices keep disconnecting?
Frequent disconnections of USB devices are often caused by power supply issues. Enable ‘USB selective suspend’ in your power settings to keep USB ports consistently powered on. If disconnects persist, consult GPK support for voltage testing and diagnosis.
How do I update the drivers for my USB ports?
You can update your USB drivers through Windows Device Manager. Right-click on your USB device > select Update driver > Search automatically for updated driver software. Be sure to install drivers from the device manufacturer rather than Microsoft’s generic drivers.
Can bad USB cables cause connection issues?
Yes, faulty or damaged USB cables are a common cause of USB devices not being recognized. Try swapping to a high-quality cable before assuming other hardware issues. Inspect cables for bent/broken pins, fraying, and loose connectors.
Should I uninstall all my USB controllers to fix problems?
Uninstalling USB controllers is a last-resort troubleshooting step, as it will temporarily disable USB functionality. Re-install controllers one at a time after restarting your PC, to isolate any conflicts. Only do this if other steps have failed.
How can I prevent future damage to my USB ports?
Handle cables/devices gently, keep ports clean and dry, don’t force connections, use high-quality cables, secure devices when transporting, limit USB hub use, shut down the computer properly, and keep drivers updated. These tips will maximize USB port longevity.
