TP link USB bluetooth device not working in my Hackintosh !?

[Tehzeeb Zaryoun]

I have successfully installed macOS Sequoia 15.7.3 in my computer (AMD Ryzen 5600G with only internal graphics & no graphics card, Gigabyte B450M DS3H V2 motherboard) but my bluetooth & wifi are not working. I'm not bothered by the wifi but bluetooth is important for me, my bluetooth adapter is a USB device, TP Link model: UB400. Does anybody know how to make this device work in my mackintosh ?

I also have a dual boot setup with Windows 11, the bluetooth device info is something like below in my Windows 11

 

 

Here are images from the macOS (Sequoia)

macOS said BCM_4350C2 even if no bluetooth present at all.

On my old HP Elitedesk G1 same TP Link UB400 worked excellent with BlueToolFixup.kext version 2.6.9.  Test with same kext was OK with old Hama USB dongle, Bluetooth CSR 2.0 EDR.
