Windows 10: I cant get com port to work on laptop with windows 11

I am trying to connect reality falcon laser engraver to my laptop and lightburn software. I am using a usb a to usb c cable to connect the latop to the laser. the software that goes with it looks for a com port. In device manager I showed the hidden item and then used the add legacy hardware, ports, standard port types. i created a com 3. the software can see the com 3, but the connection does not work.any thoughts on why the com is not working?Thanks

USB 2 port not working in Windows 10 on Samsung Notebook

Hi Tomale,

Thank you for posting in Microsoft Community.

Since all the USB ports are working and the problem is with the USB 3.0 port in the right side of the laptop, then this issue is with that particular port.

You can contact the manufacture of the laptop to get it done.

As a workaround, I suggest you to Run Hardware troubleshooter and check if it helps.

Follow these steps to run hardware troubleshooter.

• Type troubleshooting
  in search box.
• Select view all on the top left pane.
• Click on Hardware and Devices Troubleshooter and follow the prompts to
  run the troubleshooter.

Thanks.

 

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
  

 

No USB ports working on toshiba laptop

Hi guys,

Got an old Toshiba laptop, satellite l500d pslk0a-00r009
Its old and doesn't officially support win10. However I have it installed and everything works fine except USB. All the ports seem completely dead, plugging in a USB mouse I get no light on the mouse. USB flash drives don't work either. This was previously working under win7.

The issue seems to be I don't have "Generic USB hub" in device manager. Have tried to manually install it using add legacy hardware but it wont take. I have several USB root hub and others listed, but not the generic hub.

Here's what I have tried so far:

Uninstall all USB device in device managers and reboot
Confirmed BIOS is latest version
tried both legacy and compatibly USB mode in BIOS
Download and install generic win10 USB drivers
Disable USB power saving mode
Installed toshiba's service center, no updates available
Ran MS troubleshooter/fixit

I think the next step is to give up, but does anyone else have any suggestions?

thanks
