I am writing program for one of my project in which i want to disable wired mouse and wired keyboard to restrict its input events(like mouse movements , keypress events) , instead of that i will use bluetooth mouse and bluetooth keyboard. so help me to disable those.

Thanks

What I have tried:

I used following code but it blocks all inputs, not only wired devices but also bluetooth HID devices. 

[DllImport("user32.dll")]
        private static extern bool BlockInput(bool block);

        public static void FreezeMouse()
        {
            BlockInput(true);
        }

        public static void ThawMouse()
        {
            BlockInput(false);
        }
