Buttons not working - USB works

[majestictragedy]

Can you show me the output from the following commands (even just a photo from your phone or something)?

ls /usr/src/
sudo dkms build -m mk_arcade_joystick_rpi -v 0.1.5.6
sudo dkms install -m mk_arcade_joystick_rpi -v 0.1.5.6

(keep in mind that the number 0.1.5.6 might need to change based on the result of the 'ls /usr/src/' command)

I get following output:

root@retropie:~# ls /usr/src/
db9_gpio_rpi-1.1           mk_arcade_joystick_rpi-0.1.5
gamecon_gpio_rpi-1.3       mk_arcade_joystick_rpi-0.1.5.6
