Oh, I get it! I have to create two inputs with the same names. I looked at the default input settings yesterday, but didn’t see what’s different 
i’ve been trying to use the xbox 360 controller for windows and i cant manage to get the right joypad working. Might be me not knowing how to adress it or unity not supporting but your not alone in this harsh harsh battle !
If you dig deep into the forums I ran into similar issues 4 years ago. I’m afraid not much has changed since then. 
we have similiar problems with all kinds of wheel based joysticks, where you have buttons and axes combined. its really a tragedy. sometimes axes are the other way around. if the app is running for a while even there. support by logitech and thrustmaster is almost zero. we have switched one project to use the custom input manager which helped sometimes, but the randomness of the inputs still consists.
i was hoping to find a better support with the version 3 of unity, though, as its not one but many problems coexisting here. one thing might be connected to the order of usb devices how they are registering in the system, on top you have the input manager which cannot work 100% as the buttons are changing all the time.
therefore try the inputmanager, it might be a good starting point 
Yep, ran into the same problem…
Used two different joysticks and they behaved completely different.
My game is a First Person SHooter anyway… I think I’ll manage without the joystick support for now. I just feel sorry for all that time wasted.
