Windows 10: My bluetooth became an "unknown device" post W10 update

Gentlemen, nursing a Toshiba Satellite laptop on W10 v. 1904. It began life as Win 07. Subsequent to a clean install, a windows update caused my bluetooth to become an unknown device. I am sure there are instructions for fixing it and telling windows to look for and install the program that fixes it, but i've been unable to find them.

X800 GTO2 = Unknown Device

I flashed the BIOS on my X800 GTO2 last night and it is listed in the Device Manager as an Unknown Device. Is this normal?

 

No bluetooth after system restore

Thank you for your reply.

I mean I have used a Windows system restore point. I tried restoring bluetooth with commands in CMD (sfc/scannow; DISM /Online.....) and by updating and uninstalling devices in the device manager. Update did not work. Uninstalling bluetooth devices made Bluetooth disappear out of the hidden devices list.
All my steps I took worked but did not change anything in my bluetooth device list.

I am using the bluetooth of my mainboard. MSI Z370M Gaming Pro AC
My guess would be, that disabling the bluetooth network adapter before using a system restore point, disabled Bluetooth after using the system restore point.

In the device manager I get this message in the USB Device list for a unknown USB Device:
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.

 

Unknown USB Device - Bluetooth Dongle

I have a generic bluetooth dongle that I got several years ago. I tried to use it today on my Windows 10 PC and I got an error saying it wasn't able to install the drivers.

The device manager says it cannot find the device descriptor.




I've tried different USB ports (USB 2 and USB 3) with the same result. I ran SFC which returned no issues. I have also updated the drivers for my motherboard with the same result when I plug the dongle in. On a whim I even tried it in another Windows 10 PC where it worked immediately.

So to summarize:

• Worked in previous versions of Windows (XP and 7)
  
• Works on other Windows 10 PCs
  
• Works in Ubuntu and OSX
  
• Totally generic, no manufacturer or model number on the casing
  

This question appears similar but provides no actual solution. I am completely baffled, any suggestions?

EDIT

To throw another spanner in the works, I just plugged it into the USB port the side of my screen and it worked immediately. I would still like to know the reasons why it still won't work in the original ports.
