GetButton("Joy_button0") will not return true on startup.

I have a custom controller that uses a BU0836X Joystick board.

One of the buttons on the joystick is a kill switch that can lock in a upstate (true) or in a downstate (false). I want to get the initial position of the button when the game is launched, it can be up or down. Here is my code:

 function Start () {
     eStop = Input.GetButton("Joy_button0");
     print(eStop);
 }

When the button is down/false I should get false w$$anonymous$$ch works just fine. When the button is up/true I should get true but I am always getting false.

When the run Input.GetButton("Joy_button0") from Update() I also get false initially regardless of actual button state. But if I $$anonymous$$t the button down/false and release to up/true I then get true w$$anonymous$$ch is the expected result.

Anyone know why the button is mapping to false initially? and how can I get the correct state of the button on game launch?

Thanks very much.
