[Solved Mostly]Can't read joystick properly

Here is my Joystick test(part of a GameWindow code and I use VS debugger):

protected override void OnUpdateFrame(FrameEventArgs e)
{
    base.OnUpdateFrame(e);
 
    if (Keyboard[Key.Escape])
        Exit();
    int cont = Joysticks[0].Button.Count;
    for (int i = 0; i < cont; i++ )
        if (Joysticks[0].Button[i])
            throw (new Exception());
}

As you can guess by the title, no exeption is thrown when I push all the buttons!
I also check that the I have one and only one joystick by this test:

protected override void OnUpdateFrame(FrameEventArgs e)
{
    base.OnUpdateFrame(e);
 
    if (Keyboard[Key.Escape])
        Exit();
 
    int cont = Joysticks.Count;
    if (cont == 1)
        throw (new Exception());
}

And as you can guess, the exeption was thrown.
(Please don't critic me about my tests that they are'nt like NUnit and etc. :-) )
My joystick is made by Xcom and it looks like a standard Playstation's joystick. Here is a picture of it(sorry about the size):

It's fully supported by DirectX, and I play TrackMania with it without problems.
So what is the problem here?
