If your USB port suddenly stopped working normally, you need to identify the root of the problem to be able to fix it. But before you proceed, you need to be sure that the port is faulty and not the device you are trying to connect. Also, make sure to follow Laptop Verge for different troubleshooting tips.
First of all, let’s test the port by running troubleshooting steps to make sure the issue is not related to the device. You can do this by connecting the device to another USB port; if the connection is successful, then the problem is with your USB port.
On the other hand, if the device remains undetected, then you probably have a faulty device. If you have a problem with the USB port, it will be noticeable as the devices won’t connect, and the operating system you are using will show an error message.
Before you start your troubleshooting steps, check to see if there is any dust in the USB port, the best way to do this is by shutting down the laptop so you can have a better look. There is a chance that the accumulated dust is the thing causing the problem.
This is because dust reduces the airflow, which causes the system to overheat, resulting in reducing the laptop performance. You can fix this issue easily with a vacuum cleaner or a can of compressed air.
After you’ve cleaned the USB port, grab a USB cable such as a flash drive and try to wiggle it around gently. If the driver feels loose and still moves up and down, then it is probably a hardware problem.

Remove and reconnect your USB/USB cable
If you think your USB/USB cable is not working, you should first make sure that the port itself is not faulty. To test this, try using your USB in a different port. If it works, then the port is faulty and your USB is working just fine. If it does not work then there is a high chance that your USB is faulty and needs to be replaced.
Update your device drivers
