Kega Fusion 3.63x – Linux controller problem

Hi,
I’m using Kega Fusion 3.63x on linux mint 17.1 64 bit. It works very well, but I can play only with my keyboard. If I use my PS2 controller with USB adapter, Fusion doesn’t detect it. My joypads (2) are successfully detected and I found them on /dev/input/js1 and /dev/input/js2. I tried jstest and all keys works very well. When I open the controller tab in config options in Kega Fusion, I don’t see the joypad into the combo menu. I remember using my joypads with success in the past with Fusion and older linux distro.
What is changed?

Thanks

PS: Sorry for my bad english
