MP 1,1-5,1 Bluetooth problem Mac Pro 2009 (5.1) Asus bt400 dongle

[playpiano]

Hi,
my configuration:
Mac Pro 2009 with 2 processor Upgraded to 5.1 firmware.
48 GB RAM.
Nvidia Geforce GTX 680 2GB (firmware modified with MAC one).
Pcie NVME adapter with 1 TB NVME storage.
Pcie USB 3 adapter (4 USB-A port + 3 USB-C port).
Ventura 13.2 with Opencore Legacy Patcher 0.6.1.

Working that is a pleasure but not bluetooth, I know the USB 1.1 problem, I have removed the internal bluetooth module and try to use an external bluetooth dongle, the Asus BT400 attached to one port of the Pcie USB 3 adapter.
I've tried everything (reset SMC, NVRAM etc.).

Even after removing internal bluetooth mini-board about my Mac still shows it as present (is it normal?):

The dongle is seen:

But it does not appear in the Bluetooth section (se the first image above) and bluetooth does not work at all.
Tried all the commands I know:
sudo pkill bluetoothd
sudo nvram bluetoothHostControllerSwitchBehavior=always
Deleted related .plist file

Someone can help me?

Thank you

I also tried the ASUS BT 400, it don't works in Ventura.

I’ve tried this one also, it doesn’t work in Monterey- haven’t gone to Ventura on old Mac pros.

I used the wifi upgrade kit from eBay which replaces the built in wifi and Bluetooth and connects to the stock antenna.

This one should work:

BCM94360CD. Connect the wires as instructed, be careful connecting the bluetooth antenna wire, the connectors at the ends are extremely fragile. A tweezer helps with this.


This is the old one BCM94322MC:

And this is the new one installed:

The old bluetooth module is not used anymore:

That "BT" cable connects to the extension cable coming from the BCM94360CD.
