title: WMI: How to differentiate between Wireless mouse and touch screen
body: <p>I am using Win32_PointingDevice class to detect mice connected to the system. I ran my device discovery script on a machine which has touch screen. The discovery shows up with 3 pointing devices, directly connected USB mouse, wireless mouse and touch screen. My question is how to distinguish between USB mouse with touch screen. </p>
  
  <p>If Win32_PointingDevice class doesn't provide information then are there any other methods which I can use to get mouse and touch information.</p>
  
  <p>This is extension to my previous question at <a href="https://stackoverflow.com/questions/1746689/wmi-class-for-wireless-mouse">WMI Class for wireless mouse</a></p>
