NucleusCoop detects both Steam Controllers as one

[Hugo01]

Hello, this is a problem I've been struggling for the past 5 days and I just can't find any solution

The goal is : Play any game using 2 steam controllers
The problem: The software detects both controller as the same, inputs are mirroed

1. First of all I launch NucleusCoop using gloSC which makes the steam controller detectable, if I try to use the software without it the gamepads doesn't show up
2. So after doing that the software is able to actually detect 4 gamepads, but I only have 2 (Maybe because 1 SC Controller actually means 1Keyboard+1Mouse? maybe that is the issue, I don't know...)

3. No matter which gamepad I choose, even if run all of the 4 instances the inputs are always the same. Both controllers acts equal like there's no second controller, for example, If I press forward on controller 1, all instances move forward and if I press forward on controller 2 all instances of the game also move forward.

Any kind of help would be much appreciated, thanks
