Hackintosh with MSI Z370 A Pro Motherboard BT Problem

[Fritz Heckert]

Hackintosh with MSI Z370 A Pro motherboard
Intel i3-9100
34GB DDR4 RAM
AMD Radeon XR6600XT

This issue specifically concerns macOS Sequoia 15.7.4

The problem is that neither SMBIOS MacPro7,1 nor SMBIOS iMac 19,1 allows a BT4.0 USB Bluetooth adapter to work.

A UART BT device (ghost device) is always displayed, which doesn't actually exist, see here from the system report - Bluetooth:

Bluetooth Controller:

Address: NULL

Status: Off

Chipset: BCM_4350C2

Visible: Off

Firmware Version: v0 c0

Supported Services: 0x392039 < HFP AVRCP A2DP HID Braille LEA AACP GATT SerialPort >

Transport: UART
Vendor ID: 0x004C (Apple)

I checked ChatGPT, but it only gives nonsense.

Does anyone here perhaps have the same motherboard and use Bluetooth?

I'm grateful for any help.

My Bluetooth USB dongle is a:

BCM920702 Bluetooth 4.0:

Product ID: 0x21e8
Manufacturer ID: 0x0a5c (Broadcom Corp.)
Version: 1.12
Serial Number: 5CF3706681C8
Speed: Up to 12 Mbps
Manufacturer: Broadcom Corp.
Site ID: 0x14500000 / 2
Available Current (mA): 500
Additional Operating Current (mA): 0
Integrated: Yes

It is also correctly mapped internally to USB port HS09 using Hackintool, with port 255.
