Terrible! USB Port Not Working!

USB, which stands for Universal Serial Bus, is an industry standard for short-distance digital data communications. A USB port is a standard cable connection interface for computers and consumer electronic devices.

With the USB port, you can connect the USB drives to your computer or electronics device and then transfer digital files. In addition, the USB port can also be used to supply electric power across the USB cable for the USB devices which need it.

Usually, there is more than one USB port on the machine, and they are important interfaces for you. However, not everything just goes smoothly when you are using the computer. USB port not working Windows 10/8/7 issue may happen suddenly.

For example, some users from the Microsoft forum reported that their Surface Book 2 USB ports not working and they still need to use the USB port to transfer file between USB drives and computer. Is it possible to fix this USB slot not working issue?

Absolutely, the answer is YES. You may also encounter this issue. In the following part, we will show you some possible ways which can solve this USB port problem effectively.

Best Fixes for USB Port Stopped Working Windows 10/8/7 Issue

Fix 1: Restart the Computer

Sometimes, you are just very lucky enough to fix this USB socket not working issue by restarting the computer since many things get refreshed under the hood after you reboot the computer which can eventually repair some different problems.

This is the easiest way and it costs very little time. So, just restart the machine to have a try.

After rebooting computer, please connect the USB drive to your machine to see whether it can work normally. If yes, it means that the USB port not working issue has been solved itself and there is no need to worry about it.

If unfortunately USB port not working on startup after rebooting the machine, you need to move on to the rest solutions to fix the USB port problem.

Fix 2: Inspect the USB Port Carefully

Normally, the USB port is pretty robust. However, you can see that the port is wide open when there is no device plugged in. This means that debris like dust or food is particularly easy to access the USB slot.

So, when the USB port not working issue occurs, you can take a close look at the USB port to see whether there is anything stuck inside. If there is, please shut down your computer and use a thin plastic or wooden implement to remove the obstruction gently.

Besides, if the USB port internal connection is loose or broken, USB port not working issue can also happen.

How to verify this?

One way is to connect the USB drive to the computer and then gently wiggle the connection. If it keeps connecting and disconnecting all the time, there should be a physical problem with either the cable or the USB port.

If you can feel a great deal of movement, it means that the board which is supposed to be connected to is bent or broken.

Regardless of which of the above two conditions occurs, we think you’d better take the machine to a professional.

While, if the USB port seems OK physically, you may need to try the next solution.

Fix 3: Plug into another USB Port

In general, the computer has more than one USB port. Thus, a good way to rule out a single broken USB port is to remove the USB drive and then plug it into another USB port.

If the USB drive works normally after plugging into another port, it means that the first USB port may have a physical issue. If you want to use it, you need to ask a professional for help to repair it.

Perhaps, it’s time for you to try the following method if the USB device still doesn’t work.

Fix 4: Use a Different USB Cable

As a matter of fact, USB cable failure is more common than USB port failure. Thus, if you are using a USB cable to connect the device to the computer and you have another USB cable at hand, you can swap to another cable to try whether the USB port can work normally.

If the USB device starts working, you will know that the former is broken. If the USB device is still not working, you need to go to try the next solution.

Fix 5: Plug the USB Drive into a Different Computer

If there is another PC handy, you can connect the USB drive to it to see if it can work as normal.

If the USB can be used as normal, it indicates that all the USB ports are not working on the other computer. Then, you need to try to fix the faulty USB ports.

If the USB drive still can’t work, the next way may be helpful.
