I bought the EG usb encoder with buttons ...a set :

After connecting all I set the buttons in steam.
In big picture under settings.
It’s recognized and set.

Windows recognizes it’s also . In the game controller settings I can use the buttons...everything is finde there too.

But ingame, when I start FX3 the diy arcade controller is not regigized.

Have I forgot something?
Do I need a additional software?
