I've installed High Sierra on my desktop PC, the detailed configuration is in my signature. I've been trying to drive Bluetooth on BCM94352Z(Wi-Fi Bluetooth dual module ngff), and it seems there is something wrong with the USB driver.
I tried two different usb drivers, GenericUSBXHCI.kext and FackPCIID.kext with FackPCIID_XHCIMux.kext(I'm using the latest version downloaded from"bitbucket.org/RehabMan/").
    When using GenericUSBXHCI.kext, all usb ports are functioning well but there is no information in USB under System Information. And I'm also suffering from a really slow shutdown(I remember seeing codes like waitting for my keyboard and mouse but timed out). I used CoreMediaIO.framework and SPUSBReporter.spreporter and finally there are information in USB under System Information now.
      ​​When using FackPCIID and FackPCIID_XHCIMux.kext, several USB ports are not aviable(I can still charge my phone using these ports, but the PC can't recognize it), but in USB under System Information there are information about the USB Tree, but only one. I did a little more, using AIDA64 in Windows 10 try to identify the ports. In AIDA64 there are two USB Controller, one is USB 3.1 and another USB 3.0. And the problem is with the USB 3.1 one cause every ports under that USB Bus is not working(my Bluetooth is on USB3.1 BUS port 10, that's how I know my problem is with the USB).

      I'm now using GenericUSBXHCI.kext and I can see the Bluetooth device in the USB tree, but I still can't get it working after trying many different methods...so I think maybe the problem is still with USB. Any idea what to do?
