I think the main problem with no Bluetooth showing up for this card is the failure to correctly activate the USB port that the Bluetooth controller needs to be connected to under macOS.
Just because something works under Windows does not mean it should and will automatically work under macOS.
The majority of people seem to fail to understand that Apple's USB workings are not the same as Windows.
If you have not identified all the active USB ports on your machine, and then created a customised SSDT-UIAC, which you have saved to EFI/ACPI/Patched folder in your EFI partition then the USB ports may not function correctly. Commonly this means that the BT USB Controller is not active.
The way to check to see if you have an active USB BT Controller is to open 'IORegistry Explorer' and inspect the USB ports to see if you have an active USB BT - see screenshot showing an active BT controller on my Hack:

If you find you don't have an active USB BT Controller then you now know what to do, follow Rehabman's guide to create a custom SSDT -

Corpnewt has also created a Python script called 'USBMap' for mapping out USB ports, which can be downloaded from GitHub - Py script for mapping out USB ports and creating a custom SSDT or injector kext (WIP) -

For both routes it is necessary that the system ports be correctly identified for both USB 2 and USB 3 usage. The easiest way to do this is to have a blank/empty USB 2 pen drive and another empty USB 3 drive that you can quickly and easily plug in to each port on your system, one at a time and create a list of the ports that are identified in IORegistry Explorer or USBMAP, it is the same using either process.
I used Rehabman's process as it has been around longer and I understand what is being asked, as I have had to follow this process multiple times, once for each of my Hacks.
