open device mangier and connect the device you wish to disable go down to usb and the joystick will be listed click on the icon and a window will open at the bottom of it will say use this device (enable) click the drop down button and click disable the device now won't work until u rein able it. (it may report the device not working witch is ok) also if something opens up when you insert the joystick like a window it shouldn't appear doing this doesn't disable the usb only the device in this case the joystick. finally you don't need to do this to every usb opening just to one device manager can be found in start my computer (right click then click on manage) click device manager usb really finally you probably need administrative rights / be an admin on your pc also it should name the joysticks but thats not guarentied The joy stick might be under sound video and game controllers
