Using a controller, there is no way to use a melee weapon, however the left trigger being used to shoot maybe you should add this control to the same button.

Native controller support is, for lack of better term, garbage.
I am currently making an Xpadder profile which I will post as a Steam guide and on Xpadder.com when it's ready; give me a couple days.
I feel that it works fairly well. It's based off my Arma 2 profile, not too much different.
It could use some tweaking, but I'm also saving room for more possible key functions to DayZ.
I never did make that Steam Guide.... Though, someone else did for their own profile.
