Solved Controller doesn't work with GameCube emulation

[Poupou]

hello,
I have actualy a troubleshooting with the gamecube emulation, the game run fine but no controllers are detected,
Recalbox is on USB Key and i use it on dedicated computer (i5 /8gRam/GTX 660m)
I have two controllers, Generic USB and dragonRise (free box controler)

This is a screenshot of dolphin conf controller:

Is someone have an idea for this troubleshooting, please ?

Best Regards,
