The computer’s USB port does not work: causes and solutions

The computer’s USB port is one of the most fragile pieces of hardware on the PC because it is exposed to dust and dirt, which deteriorate it over time. In addition, it can also be affected by viruses, buggy updates, lack of power, etc.

This way, if you are having problems with the USB port on your PC, here you will find what could be the possible causes that are causing the failure. Likewise, also the solutions that exist for each type of problem.

Causes of a USB port not working

If your USB port is not working, this may be due to one of the following causes:

– Dirt: If you have not performed maintenance on the port, dust could be blocking the connectors to the point that they will not make contact with your peripherals. In this case it is necessary to clean the USB port.

-Physical damage: On the other hand, it could also be physical damage; it is normal that due to use the port loses some of its connectors, which will prevent it from pairing with other devices.

– Lack of energy: USB ports have a small amount of power that is used to power the devices you connect. When there is little or no power, the port will fail to pair with the device.
