Hi John,



Welcome to Microsoft Community and thank you for posting your query.



Based on your description, the issue seems like HooToo USB port driver is outdated. Let’s try simple steps and check if this help.



I recommend you to update the HooToo USB port driver and check if this helps. Follow the below steps.

• 
  Press Windows key + X and click on
  Device manager.
  
• 
  Click on Universal Serial Bus to expand and right click on the port device and click on
  Update.
  

If the issue still persist, I suggest you to go to the USB manufacturer website and install the driver for Windows 10. If the available USB driver is not for Windows 10, try installing the driver in compatibly mode and check.

  Select Compatibility tab.
  
• 
  Check Run this program in Compatibility mode.

  Let the driver install and then check the functionality.

PCI Serial port driver.

If your computer came with a serial port built into it (pretty rare these days), go to the support site of your computer's manufacturer, enter the identifying information about your specific model (probably the serial number), and look for the driver for
the serial port.

If you have difficulty doing the above, please provide the make and model of your computer (and its serial number).

If you installed an add-on PCI card for the serial port, what is the make and model of that PCI card?

Otherwise, right-click on that entry in Device Manager and select the "Details" tab.

Select "Hardware Ids" in the drop-down list under "Property"

Copy the first line in the "Values" box and paste into a Google search.

If you get no hits when searching for the entire first line, search only for the VEN/DEV information.

Using the screenshot below as an example:

Search for PCI\VEN_14F1&DEV_10B4&SUBSYS_9300141D&REV_89

If no hits, search for PCI\VEN_14F1&DEV_10B4

Alternatively, you can use one of these PCI VEN/DEV databases:

Once you know the manufacturer and model of the serial port, you should be able to find the driver for it. If at all possible, avoid third-party driver download sites. Look for the website of the device manufacturer.
