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
  

 

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

Hi, I'm Robinson, and I’m happy to help you today.

I know how frustrating this may be for you but I'll do my very best to help you.

This problem is caused when the driver is not installed, is installed in the wrong version, or is not compatible with Windows 11. You will need to check the manufacturer's website for the latest version and install the driver manually.

Once you downloaded the latest driver version:

1-Open the Device Manager

2-Connect the USB Serial Port

3-Click to expand the Other Devices, then check if it is recognized as an unknown device, or click on "Universal Serial Bus Controller" and check if it is recognized

4-Right-click on the USB Serial Port or unknown device and select Update driver

5-Click on the option "Browse my computer for drivers"

6-Click on the option "Let me pick from a list of available drivers on my computer"

7-Select "Multi-port serial ports" from the list and click on next

8-Click on "Have disk..." in the bottom right corner

9-Click on Browse and select the driver that you downloaded and follow the instructions
