title: controlling mouse with pyusb
body: <p>I have to make a application, that do the followings:</p>
  
  <ul>
  <li>disable that the given usb mouse move the pointer in the screen (just the given, not all  mouses).</li>
  <li>get the coordinates of the mouse pointer</li>
  <li>change the y coordinate of the mouse pointer</li>
  </ul>
