Buttons not working - USB works

[majestictragedy]

From your 'ls' output, you can see that  mk_arcade_joystick_rpi-0.1.5.7 is the latest (highest) version.

Please try:

sudo dkms build -m mk_arcade_joystick_rpi -v 0.1.5.7
sudo dkms install -m mk_arcade_joystick_rpi -v 0.1.5.7

and then reboot and let me know if it works after that.

I got following output:

root@retropie:~# sudo dkms build -m mk_arcade_joystick_rpi -v 0.1.5.7

Module mk_arcade_joystick_rpi/0.1.5.7 already built for kernel 4.14.71+/4

But I installed it already still not working after reboot. What I am doing wrong?
