port COM and LPT in the Devices Manager are not appearing

Hi Luis,


I suggest you follow the steps to check for hidden devices, and check if it helps.

1.Press Windows + X and click on Device Manager.

2.Click on View menu and select Show hidden devices. See if this helps in getting the ports to list.

3. Expand the Ports under device manager. Uninstall any entries which appear grayed out, then restart.

4. Right-click your computer name in Device Manager and click Scan for hardware changes. Device manager scans your system and automatically reinstalls your device.

If the issue persists, then I recommend you to install the latest drivers for your motherboard.

Do let us know the result.

Thank you.
