Snow Leopard 10.6, does anyone know of a small USB Bluetooth dongle that's compatible?

[M3Bolt]

First off, I do apologize as this is clearly NOT the correct place to post this. I am unable to post in any other subforums, even though I read the rules. 

I have an old Hackintosh that I love, and am doing a hardware modification project with. I need to use the Apple bluetooth mouse and keyboard with it, but my machine does not have Bluetooth as it's an MSI Wind U100. I do know there is/was a BT module that was able to be added, but the old Wind forum, and thus the trove of information there, is gone with time. I'm not sure how to find that module or if its even compatible. 

I am settling for a USB adapter, but I can't find any that specifically state compatibility out of the box with Snow Leopard.

Can anyone give me any advice on this? My project may be dead without it!

Thank you, and thank you for keeping OSx86 alive.

You can get one of those bt 4.0 dongles that use BCM20702A0 chip (i.e iogear gbu521, asus usb-bt400). Oob since Mountain Lion. But for Snow Leopard, you'll need to patch BroadcomUSBBluetoothHCIController.kext to add device-id and vendor-id of the bluetooth dongle. The guide of patching BroadcomUSBBluetoothHCIController.kext can be found here.

I have a dongle which was working from MacOS 9 up to Big Sur. But you don’t have a chance to buy similar old device.
