Bluetooth driver issue

[Azza ☠]

The "BCM20703 Bluetooth 4.1 USB Device" won't function on Windows 11 with Core Isolation / Memory integrity enabled.

This is due to the file "btwusb.sys" most likely not been digitally signed?

Is there any way around installing this driver or using something else? I have bluetooth running on the PC just fine. It's only when the HTC Vive Linkbox is enabled, that bluetooth fails.

Have a HTC Vive Pro Full Kit with version 1.0 controllers and base stations.

Using Windows 11 Pro - 64 bit (21H2)

This device has a 12.0.1.1104 driver available signed/packaged 2018-07-30, Windows update (and most vendors) do not supply it, has anyone tried it?

Edit

NVM, the faulty component is NOT part of the driver itself, but a part of the widcomm bluetooth stack package, I do not know why SteamVR and HTC can't get updates for this considering it has not been discontinued.

I could not install the 12.0.1.1104 driver. It says "not compatible".

I always turn the base stations off when not in use, and they're never going to have a FW update from where they are now.. so no need to have the BT driver working...
As long as VR/headset etc keeps working...

The Solution is here :
Disable Memory integrity in windows 11 :
Go to Windows Security -> Device Security -> Core isolation Details - Turn of Memory Integrity - then you will be able to update/install your driver after a reboot.

Starting Steam VR will ask you for a driver update, if this is your first install.

- This worked for me. stupid windows

Not a solution, but it probably will never be solved.

It's not a solution for me. It's rather adding a possible security hole.

I've given up on them however fixing this issue, it's been years. Affecting both Base Stations version 1 & 2.

I've rather been using a Smartphone app called "LightHouse PM"

Lighthouse Power Management:

Enable access to your bluetooth and you can toggle each Base Station within close range of it. It works well for either Base Stations 1 or 2. A bit manual to open the app each time, but just a click of a button to use.

I have to downgrade back to Win 10 x 64 version to get this issue solved. Disable all other Bluietoothdriver and restart SteamVR.

This is the solution. V1 base stations haven't received an update for ages, nor will they in the future. Disable Bluetooth, remove offending driver with pnputil if you've disabled core isolation. Keep Core Isolation activated or enable it again and feel safe. (r) Remember, the controllers pair with the headset, not the Bluetooth link box. Power management should be loss, not computer security.

Its not that hard switching stations off and on.

Thanks. This worked. I just bought my buddies OG Vive for $200. I'm running Windows 11.
