              }
              UsbMouseModule.getInstance().onGenericMotionEvent(event); // Comment out if you dont need all events

import KeyEvent from 'react-native-keyevent';

  import * as UsbMouse from 'react-native-usb-mouse-android';
  
  useEffect(()=>{
    const listener = UsbMouse.onMouseScroll((event: GenericMotionEvent)=>{
        console.log('Mouse Scroll', event);
    });
    return ()=>listener.remove();
  }, []);
