Because it is important to identify where the problem arises in order to fix it, it is recommended that you try to connect another USB drive to the defective port.

If the new USB drive is being read properly, then it is clear that your USB port is not the issue, so that makes the USB drive the culprit.

If the USB drive is not being read, then we can assume that the USB port might be defective.

Note: Make sure the new drive is compatible with the USB port.
