If you are completely sure that the USB Device works on other computers and not on the available USB Port of a particular computer, you can carry out the following procedure to validate that it has not been detected incorrectly:
- Disconnect and reconnect the USB Device in the USB Port: Up to 3 times to try to be recognized.
- Restart the computer and perform the previous step again.
- Turn off and unplug the equipment from the electrical outlet for 1 minute, and retest the first step on this list.

- Run the Device Manager and on the item «Universal Serial Bus Controller» look for the unknown USB Device (with problems) and right click on it, to manually proceed to look for changes in the hardware, or uninstall it and then reinstall it and update it, if necessary.
3. Cause: USB port automatically blocked by the Operating System
- Test that the available USB Port works with other USB Devices to prove that it is operational and not disabled or damaged.
- Disable the Windows functionality called: USB Selective Suspend Settings. This can be done through the

Or through the Device Manager to try to find changes in the Hardware automatically or manually and thus achieve their detection and correct configuration (installation / update).
- If you are sure that the USB port was working recently, you can try to verify and correct its current status. To do this, you can check the BIOS / UEFI Configuration of the USB Ports. Or, failing that, restore the Operating System to a previous state, from the date on which it was sure that it worked. This is because some Windows updates can cause configuration problems in the USB Ports.
- Try different USB Devices on that USB Port to fully validate that it does not work, that is, that it is damaged.
5.- Cause: Various problems in the Operating System

«Panel de control -> Sistema y Seguridad -> Opciones de Energía -> Opción: Elegir el comportamiento de los botones de inicio y apagado -> Opción Cambiar la configuración actualmente no disponible -> Desactivar Activar inicio rápido (recomendado)»-> Finish saving the changes and then close the window and restart the computer. - Check that all updates to the Operating System are perfectly executed.
