@dam yes i tried, now i have another problem ... update requested by recalbox, i allow and after reboot: lighting
yellow

I am in the same case as you, impossible to pair my ps4 controller ,
I did what Paradadf said but unsuccessfully.
The recalbox sees my controller but when I select it, it search ... then tells me "can not associate the controller"

For info: Raspberry pi3 b +
