Do I need to do USB mapping for Fenvi t919 to work?

My USB Ports are all working. The only thing that doesn't work is the bt of my Fenvi t919.

Can I somehow just declare my internal usb ports as internal so my bt works without mapping every single port? Because I have many usb ports and no usb 3.0 to try and figure out which port is which right now.

Thanks for any advice
