Game Input MultipleXer

I get error message joystick not found.

I'm using teensy and bluetooth module to pair. DS4 is connected over usb cable to pc, ps4 is powered, Logitech driving force pro is powered.
For config I used Driving force GT_G29 and remaped controls. Sved and tryed to run. After that i'm getting that message.
What am I doing wrong?

Thanks

Joke aside, the bluetooth connection method can't be used to emulate a G29.
You need to build a DIY USB adapter as explained on the wiki.
