Unity reading brand of controller

So I'm making this game that uses the guitar hero, and/or rockband controller to move the character. A problem coming up is that I don't know how to tell/ask unity to check which brand (xbox or ps) controller is being plugged in. When you plug in a controller it outputs the brand of controller in consul, so I was wondering how to access that to tell a custom input manger to switch controls based on which type of controller is put in. I looked into Input.GetJoystickNames() but that just returns how many controllers whereas I'm concerned with type. Any ideas, thoughts?
