Can't make USB Bluetooth work

[Ephasme]

Hi everyone, I just made a Hackintosh, everything is working perfectly except for the USB stick which should provide bluetooth.
I bought this model:
https://www.amazon.fr/gp/product/B015R7OA1U/?tag=tonymacx8607-21
As advised here.

I put the 'BrcmFirmwareRepo.kext' and 'BrcmPatchRAM2.kext' in /System/Library/Extensions

I dont see anything working...
When I launch kextstat I don't see the kext loaded.
When I try to load them by hand with kextload I receive an error:

/System/Library/Extensions/BrcmFirmwareRepo.kext failed to load - (libkern/kext) authentication failure (file ownership/permissions); check the system/kernel logs for errors or try kextutil(8).

Please help me...

You cannot just copy kexts to the /S/L/E, you need a dedicated tool like KextUtility or KextWizard to do it for you. That also fixes the permissions right off.
