Broadcom wifi/bluetooth combo card issues, bluetooth doesn't recognise devices

[giovanealex]

Hi, guys. I’m facing a problem with a wifi/bluetooth combo card. I bought this PCI-e 1X adapter and a BCM943224PCIEBT2 (BCM43224) card, which is a common module on Macbook Air models from 2010 up to 2012. The items were bought separately, and when they both arrived I installed on a PCIe slot of my machine running OSX 10.11.5 (El Capitan) and connected the mandatory micro usb port of the module on a USB port on the back of my Gigabyte motherboard using the provided cable. The wifi is fully recognised and works effortlessly and though the bluetooth module is present on the Preferences Pane and on OSX menu bar, it simply doesn’t recognise my Magic Trackpad and Magic Keyboard (they both are recognised by my Macbook Pro). I tried to make it recognise something else (an AirTracks bluetooth headphone), but it was to no avail. Strangely, there is a unknown device which appears on the bluetooth panel which I have no idea what it is (it is not mine for sure, it could be from a neighbour or it simply could be an error, since it doesn’t recognise my Apple devices which are in front of it). This unknown device is shown with the Magic Mouse icon, but it doesn’t connect too and it is not shown on the Magic Mouse portion of the Pref Pane. I installed Sierra and Mavericks on a separate partition to verify if it was not simply an El Capitan issue, but it worked the same way on both: wifi fully working, bluetooth present on Preferences Panel, but nothing is recognised. I’m already providing the System Information screenshots showing the wifi, bluetooth and USB Hub info for you to check what is possibly wrong here. My setup is made of an Intel i7 4770 on a Gigabyte Z97M-D3H with 16Gb of ram (2x8 HyperX modules) and OSX installed on a SanDisk SDSSDA240G. I’m using Intel onboard graphics.
Can you guys help solve this issue? Thanks a lot!

Update: I have installed both BrcmFirmwareData.kext and BrcmPatchRAM2 following the instructions here first on S/L/E then on Clover/Kexts/10.11 folder on EFI partition and things are the same. Here is a new screenshot that adds more oddity to the situation: bluetooth panel says it is "discoverable" but when you hold Option key and click on the bluetooth icon on menu it says it is NOT discoverable.
