title: What is a USB Device GUID and What does it mean
body: <p>See this Registry key:</p>
  
  <p>[HKEY_CURRENT_USER\System\CurrentControlSet\Control\MediaProperties\PrivateProperties\DirectInput\VID_0079&amp;PID_0011\Calibration\0]
     "GUID"=hex:e0,fa,66,14,00,b3,e0,11,80,01,44,45,53,54,00,00</p>
  
  <p>As you can see there is a GUID key for this Device, and it contains some Hex codes. I want to know what is GUID and what does it mean really, which info does it give me and any other important info about it.</p>
  
  <p>Any Help Really Appreciated :)</p>
