help to use a second mouse on the pc as joystick

[lucakcond]

Good morning first sorry for my English, so I have two monitors on my PC where I can play some split screen games, in the case borderlands2 on one monitor I use the mouse and the keyboard, on the other a joystick, what I want is to use keyboard and mouse in both, my biggest problem is with the mouse I can not, the way I thought was using a program that creates a second virtual mouse, and hence would turn the buttons on the joystick by autohotkey, but I do not know the names of buttons.
does anyone know any way I can figure out the names? , or to do what I want to work

Forget it, not gonna happen. As far as windows games are concerned, there is only one mouse.

But borderlands 2 have a special command that Focus both split screen, so If i remap one from both mouses tô another keys , maybe this gonna work , so i need help with this

You want one running copy of a game to take input from two separate mice?
I am telling you - never ever gonna happen.
Technically possible (The RawInput API can differentiate input from different mice), but no games that I am aware of do it.
At best, what you could do is use 3rd party software to make a 2nd mouse operate a virtual joystick (99% of software that can do this cannot do this for *just one* of your mice). However, in order to do this, you would also need to stop the game from seeing the input from player 2's mouse and applying it to player 1.
