The USB signals are wired into the WLAN slot. The problem is that the "BT enable/disable" signal on pin 51 is hard-wired to "disabled". To bypass this, you need to isolate Pin 51 on the mini-pcie connector of the AX200-- this can be done by either covering it with tape, or cutting the circuit board trace.
