Check the Physical Connection
First things first, check the physical connection between the USB device and your computer. Make sure the cable is securely plugged into both the device and the computer’s USB port. If the connection is loose, the device may not be able to communicate with the computer.

1. Open the Device Manager as described above.
2. Right-click on the USB device that is not being recognized and select “Uninstall Device“.
3. Restart your computer.
