Steam config perhaps?

does steam detect it as an elite series controller.

does it behave the same in all 3 profiles? (button in centre of controller 0 1 2 or 3 lights lit up)

mine comes up as the same bluetooth le xinput device because i have the expanded features enabled. (custom paddles) but it only comes up once. i cant change to the 360 option is that a second controller or the same one?
