USB-related issues can be caused by a variety of factors, such as an incompatible device, outdated or incorrect drivers, damaged USB ports or cables, a faulty USB port, and so on. To identify the root cause of the problem, it is important to take a closer look at your USB ports. Dirt or debris can block the port and prevent a proper connection between the computer and the socket. A good indicator that something is stuck is if the cable isn't fully plugged in.Dust can also reduce airflow and cause the system to overheat.
This is especially harmful to laptops, where overheating can reduce performance in a matter of seconds. To fix this problem, clean the USB port with a can of compressed air or a vacuum cleaner.Before you start, you can try some simple tests. It can save you a lot of trouble if you do. Restart your laptop for it to take effect and check if the USB ports are working again.
If that doesn't work, look for debris in the USB port. These ports are wide open when you don't have a device plugged in, so it's easy for debris, such as dust or food, to remain inside.Check for loose or broken internal connections as well. One way to check this is to insert the USB device and then gently move the connection. If it connects and disconnects briefly, it means that there is a physical problem with the cable or USB port.
Restart your computer and check if the USB device works.
