Bluetooth Passthrough on Asus BT400

[mstreurman]

So I had some issues with my old Bluetooth Adapter (it fried because of me accidentally hitting it while walking past my computer) so I had to buy a new one. But now for whatever reason, I cannot get it to be detected by Dolphin. I installed the LIBUSBK drivers on it with Zadig, but it keeps telling me that there are no Compatible Bluetooth Devices found and thus in the logs it's stating:
23:01:609 IOS\USB\Bluetooth\BTReal.cpp:113 E[IOS_WIIMOTE]: Failed to get config descriptor for device 8086:a2af: LIBUSB_ERROR_NOT_FOUND
23:01:609 IOS\USB\Bluetooth\BTReal.cpp:113 E[IOS_WIIMOTE]: Failed to get config descriptor for device 1b21:2142: LIBUSB_ERROR_NOT_FOUND

I tried the latest developer Dolphin extracted in a new directory, rebooting my machine multiple times, making sure that Windows 10 was up to date, reinstalling the drivers, changing USB3.0 ports to USB2.0 ports and so on.
Tried many games and of course the Wiimenu 4.3U (which is also a clean one updated from within Dolphin)
What am I missing?

So I have been able to fix the LIBUSB_ERROR _NOT_FOUND by installing the USBDK drivers but it still keeps telling me that it can't find a supported Bluetooth device. So I guess this adapter is unfit for Bluetooth Passthrough? It has some sort of Broadcom chip in it.
Or does anyone have some other idea what I can do to fix this?
