USB ok, but BT-dongle doesn't work on my X79

Did Multibeast install to Mojave on my X79, GTX 770, i7 4930K. Works well, but I just can't get the bluetooth dongle get to work.

All USB ports work. They just don't like the USB dongle. (GMYLE) The hardware definitely allows for it, I used the same setup for the last few years, and it worked without a hitch. This update broke it though.

(I also have an error message pop up after every restart that the system didn't shut down properly, but I don't mind. At this point I just need to fix the BT and get back to work. It's been days of trial and error...)

Anyone know how to fix this? Arghhhh.
