Windows 10: I am unable to see the COM ports in my device manager.

I have tried manually installing through the legacy hardware option as well but Windows does not seem to recognize it after manual installation. I am using a HP Pavilion X360 14-cd0087TU and I installed Windows 11 Home Single Language 22H2 on it.Thanks

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.

 

Unable to find USB Serial Port (Ports COM & LPT) in Device Manager Windows 11

After updating to Windows 11 I can no longer get the serial port in Ports COM & LPT from the Device Manager.

When I select Device Manager nothing shows up, I cannot see Ports COM & LPT.

These are the steps I have tried:

IN DEVICE MANAGER

• View: Show hidden devices in Device Manager (nothing happens)
  
• Scan for hardware changes
  
• Action: Add legacy hardware. Used both search recommended and add manually.
  
• When trying to add Communication Port: "Windows cannot determine the settings from this device". Does not work and have a yellow warning sign. When adding legacy hardware next time it is uninstalled since it says it does not work.
  
• When trying to add Serial Port: "The installation failed because a function driver was not specified for this device instance".
  

WINDOWS UPDATE

Making sure all updates are done (both software and hardware)

My system

• Windows 11
  
• HP Pavilion Laptop
  

 

Com Port is Missing / Ports Option Not Available In Device Manager

Hi,

Welcome to Microsoft Community and thank you for your interest in Windows 10.

COM port should be listed in Device Manager under Ports (COM & LPT).

See if you can find them. If they're not listed in the Device Manager, you can try these suggestions to see what’s preventing the ports from getting displayed in device manager.

Method 1: Check for hidden devices as below and check if it helps.

• Press Windows+X and click on Device Manager.
• Click on View menu and select Show hidden devices. See if this helps in getting the ports to list.

Method 2: Install the latest drivers for your motherboard. See if this proves to be of any help.

Device manufacturers often release updates to their drivers to enhance performance or fix compatibility issues. To get the latest driver, visit the support section of your motherboard manufacturer’s website.
