Question Windows 10 drivers for Broadcom Bluetooth module (BCM92045MD)?

I have a Bluetooth module (Broadcom BCM92045MD) in an old laptop.

Bluetooth is recognized and enabled in BIOS, etc., but Windows 10 isn't recognizing it, let alone installing some sort of drivers. I can't even locate it reliably in Device Manager, as there's more than one unknown device.

Anyone know what can be done? I tried searching the Broadcom site for drivers, but got nothing. And I'm not exactly sure how to use Windows Update properly in Windows 10, as I'm still relatively new to the OS.

EDIT: I tried running the Bluetooth troubleshooter, and it claims this machine has no Bluetooth capability, which isn't true.

Search the PCI "device id" shown under each "unknown" device on DDG, you might find a driver that works, or at least, identify which unknown device is which.

Also, check the "Windows Driver Update Catalog" web site. That's MS's site where they keep drivers and Windows Updates for all versions of Windows.

What is DDG?

And the unknown device hardware IDs are as follows:

PCI\VEN_1180&DEV_0843&SUBSYS_02271028&REV_12
PCI\VEN_1180&DEV_0592&SUBSYS_02271028&REV_12
PCI\VEN_1180&DEV_0852&SUBSYS_02271028&REV_12

I figure every model of hardware out there has its own hardware ID? If so, these are all showing up as Ricoh controllers of some kind (not Broadcom Bluetooth) on Microsoft Update Catalog.

Those three appear to be Ricoh card reader devices, and not BlueTooth.

Is the BlueTooth module in question, a factory part, or did you add it? Did you modify the BIOS whitelist to allow for it?

Does a bootable Linux Distro like Mint Cinnamon 20.2 64-bit see it as a BlueTooth device?

It's factory (option during configuration).

Bluetooth is "enabled" in BIOS.

I'll try the Linux distro bit and report back.

Mint Cinnamon reports no Bluetooth device is available. Weird.

The Bluetooth module is plugged in (I confirmed this yesterday by opening up the laptop), assuming it has just the one connector to worry about.

Did you hit the BIOS keyboard hotkey to enable / disable BT? Airplane mode?
The switch that controls Wi-Fi and Bluetooth is disabled/ignored through BIOS (I didn't physically set it properly when putting the laptop back together years ago, so I disabled it entirely to avoid problems).

Airplane mode is off.

I'm thinking either I need to open up the laptop (right down to the motherboard) and physically set the front switch properly, or the Bluetooth module (or perhaps the connector) is busted.
