Hi,
i recently bought a controller (generic Nintendo switch pro controler).
Plugin it in using USB works perfectly, but when paired with bluetooth, i can't see any inputs.
I'm using recalbox v 6.1.1 on a RPI3 & onboard BT.

=> no input at all
One is seeing as a gamepad, not the other....
I don't know what is missing, i've tried many things, like disabling other controlers driver (ps3 bluez), troubleshoot BT pairing, forcing pairing, but yet nothing worked.
Any help is much appreciated.
Thanks
