Windows 10: Restoring a missing driver (Bluetooth in my case)

I'm running Windows 10 Version 20H2, Build 19042.985. l've accidentally lost one of the Bluetooth drivers while trying to connect to my headphones, There are many posts about the "Bluetooth failed to connect" problem and many suggested remedies, most of which require uninstalling or deactivating a Bluetooth device. In Device Manager, if you click on the Bluetooth device, you're supposed to see five subdevices: Bluetooth Device, Intel Wireless, Broadcomm, Microsoft Bluetooth Enumerator. and Microsoft Bluetooth LE Enumerator. Most of the suggested remedies for the did-not-connect problem require disabling or uninstalling a one of these devices and restarting. In my flailing around for a solution to my problem, I tried a third alternative which apparently exists only for the Broadcomm device: deleting the driver. After doing that and restarting, I had not gotten a connection, but the third subdevice, the Broadcomm one, had vanished, I had also lost several other devices that had shown up previously. Restarting ordinarily restores missing components, but in this case it did not. Try as I might, I could not get the Broadcomm device to come back. Rebooting did not help. So where can I find the missing driver, and how can I reinstall it?

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.

Bluetooth not working

Hi,

For us to properly isolate the issue with your Bluetooth, we would like to know the following:

• Are you getting any error messages? If yes, what is the error message?
• Have you tried installing the latest Bluetooth driver from the manufacturer's website?

As an initial troubleshooting to isolate the issue, we suggest that you try pairing your Android phone to your Bluetooth dongle. If it connects, there is a possibility that you missed some steps in paring your headphone to your dongle. If this is the case,
we suggest that you refer and check your headphone's manual for the proper setup/pairing, or contact your headphone's manufacturer.

We look forward to your response.
