Can't pair Bluetooth devices

[Rak]

Hi there,
I was able to get Catalina running on my PC, but now I'm having troubles pairing my Bluetooth mouse + keyboard.
I could pair my Bluetooth headphones without issues, but no matter what I try, my Logitech MX Keys and Logitech MX Master 3 won't connect. They appear in the list of devices but "Connect" does nothing.

I'm using a TP-Link UB400 dongle.
Motherboard: Gigabyte X570 Aorus Elite (no built-in WIFI/BT).

What I've tried:

• Reset NVRAM through OpenCore
• Delete Bluetooth plist in Library/Preferences
• Reset Bluetooth module
• Different USB ports
• Reboot 69420 times
• Proper USB port mapping

Any ideas?

Did you properly map your usb ports?

Did you properly map your usb ports?

No the guide isn't clear to me and all USB ports work even without remapping, so...
The dongle works, I could connect my headphones.
I just can't pair any mice or keyboards.

/edit
I don't know if this is any useful, but whenever I try to pair a mouse/keyboard I get these 2 lines in Console.app from process bluetoothd...

They may work, but without proper mapping they may have issues like this.

Well it took me a few hours but I did the mapping.
That didn't resolve the issue unfortunately.

Also I just realized there's actually a "Post Installation" subforum... If a mod reads this, please move this thread...
