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?

 

Bluetooth driver for Linux.

I have an Apple wireless keyboard that use with a Linksys Bluetooth USB receiver adapter (USB BT100 Rev2). It works great with Win10 and it’s small footprint saves a ton of desk space. But when I dual boot to Linux Mint a get a keyboard missing message. Since I’m a rank beginner with a Linux, I could really use a step by step guide to finding and installing Bluetooth drivers to get this keyboard working with Linux. Thanks in advance.

 

Missing Bluetooth Driver

Early today my Bluetooth suddenly disappeared, so I went through some steps to try and fix it. I did the following:

- Changed the Bluetooth Support Service to automatically startup.

- Bluetooth troubleshot, which simply said Bluetooth was not a feature on my system, despite it working a few hours earlier.

- I scanned the drivers for updates, which they said they all were.

- And finally, I try uninstalling and reinstalling the Bluetooth driver. However, the driver has not automatically reinstalled like the tutorial said it would. I have restarted, scanned for changes, scanned for updates, and it is simply gone.

Am I missing a step, all the "official" Bluetooth drivers seem like they originate from sketchy sites and I don't want to download malware or something similar.
