Estou tentando usar um gamepad no linux (kernel is 4.16.10) e não consigo obter nenhum evento de entrada.
O dispositivo, um controlador xbox 360 falso, parece ser detectado, pois dmesg parece informar:
#dmesg when pluging in controller

No entanto, não consigo obter nenhum evento de entrada nem com jstest nem evtest (como raiz e não raiz). Mesmo com xboxdrv btw.
Alguém tem alguma ideia ou iniciativa para encontrar uma solução para esse problema?
Obrigado,
