How to Troubleshoot a USB Port

A Universal Serial Bus (USB) port is a connection type that allows different types of components, from keyboards to hard drives, to easily connect and function. A USB port utilizes a feature called "Plug and Play," which means few drivers are needed for the hardware to function properly because the operating system already has the proper drivers to run the component(s). Unfortunately USB's "Plug and Play" feature can be interrupted or corrupted by different objects such as corrupted drivers, a bad USB component or physical damage to the port.

Step

Determine if there is any physical damage to the USB port, such as a burned port or bent USB pins in the port.

Use any working USB device to test the ports. If the device doesn't function, you will receive errors such as "Unrecognized USB device," or nothing at all will happen.

Step

Remember the last items that were installed that could have caused this issue, such as a bad USB component or software that altered the configuration of the USB port.

Step

Uninstall the software, or replace the component with a working USB component.

Step

Test the USB port once the computer loads.
