    If two same USB HID joystick is connected at the same time.
    How can I get Directx Joystick ID from USB HID Joystick instance?
    I want to know what HID instance is 1P or 2P.

    I expected next API can get Joystick ID or some relation(something like
    pointer) with DirectX joystick.
    But I can know nothing about DirectX joystick.

    HidD_GetPreparsedData(Handle, &Ppd);
    HidP_GetCaps (Ppd, &Caps);

    Values of two USB HID joystick is same
    (Caps.reserved is different but I can not know what it means)

    I want to know which USB HID joystick is which DirectX joystick.
    (or the DirectX joystick ID of USB HID joystick)

    Or I can know DirectX joystick ID next DirectX API

    g_Joystick[*pJoyCount].dwID = dipdw.dwData;

    Can I know the pointer of USB HID joystick instance with DirectInput API?
