Buttons not working - USB works

That's interesting.  Okay.  Please try this, then.

Code:

sudo dkms remove -m mk_arcade_joystick_rpi -v 0.1.5 --all
sudo dkms remove -m mk_arcade_joystick_rpi -v 0.1.5.5 --all
sudo dkms remove -m mk_arcade_joystick_rpi -v 0.1.5.6 --all
sudo dkms remove -m mk_arcade_joystick_rpi -v 0.1.5.7 --all

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

I have seen it once or twice before where it somehow gets confused about versions.  The above commands should try to remove all the potential old versions.  Then it should build the latest version and then try to install it (forcefully).  I sure hope this works.  I don't know why it would be confused, though.

EDIT:  Actually, I know why it had a problem when you first did the update.  I wonder if after that you ended up accidentally trying to install an old version and that's what got it confused about which version it was supposed to install and use.

Thx for your help again. Still not working. :/
Do you have another idea?
