FIX RAW Input ID

[xbrunox]

Hi All i've a problem with the roms that use raw input, 2 lightguns, (lost world, ocean hunter, la machine gun) the ID Controllers isn't Fix. one time a lightgun is gun 02, one time the some gun is gun 01 or gun03.
This is a note problem with USB Id that mame has fixed with the controllers file that assign a contreller number to a specific HID USB value.
there is a solution for supermodel?
i've found something here but i cant understand.
