USB Port Doesn’t Work: How To Resolve This Problem?

Did you find your computer’s USB port not working? We bet it feels frustrating but do not panic yet! In this article, we have collected some of the best simple tricks that will help you fix the problem and bring things back to normal. Let’s see what steps you can take.

Try Restarting Your PC

Although it doesn’t always work this way, many failures still can be fixed with a simple restart. Thus, if you are lucky and there was no severe system breakdown, turning your PC off and on again should work for you.

Once you power it back on, you should test the functioning of your USB ports. If it works, you shouldn’t worry about it. Otherwise, you can move on to more complicated steps.

Clean Up The Openings

Since USB ports stay open nearly 100% of the time, all sorts of dust, crumbs and other garbage can easily get inside them. Thus, before you start looking for possible reasons of improper functioning, take a look at the port itself to ensure it’s clean, and nothing got stuck there.

If you see any debris inside, power off your device and clean it up with a thin item made of wood or plastic (for example, a toothpick).

Also, you should check whether your port isn’t too loose, as this can be another reason for a breakdown.

Use Another Port

If none of those mentioned above methods didn’t work for you, try using another port to check whether you have only one of the ports broken or if it is a major system failure.

Change Cable

Sometimes the problem may occur not because of the ports’ damage but because of a cable failure. Thus, you want to make sure that you try using several cables to ensure that the problem wasn’t caused by it.

Alternatively, you could also try connecting your device to a different computer. Or, you may try connecting another device to the same computer. Both methods will help you understand if the problem occurred with the device itself.

However, if even in this case it doesn’t seem to get connected, follow the steps described below to fix the problem.

For Windows

If you own a Windows PC, you should check the device manager to make your ports work again. Here are the steps you should take to scan your system for any changes with Device Manager:

  1. Right-click Start then left-click Run
  2. Type “devmgmt.msc” and hit OK to launch Device Manager
  3. Press on the name of your PC with the right mouse button
  4. Click with the left mouse button on scan for hardware changes

When the check is over, try connecting any device again to see if the problem was fixed or not. If your USB port still doesn’t work, there might be an issue with its controller. Here is how you can restart it:

  1. Start with step one and two as described above
  2. In the list, find Universal Serial Bus Controllers
  3. Press on the arrow located right next to the little USB cable so that it points down instead of to the right
  4. Click on the first USB controller with the right mouse button and uninstall it, then do the same with all the other USB controllers
  5. Restart your computer to let the system reinstall all the missing elements
