title: Control USB port's power?
body: <p>Does anybody know how to control USB pins on a certain USB port? I think it is definately possible in assembler but what about C++ or C#?</p>
  
  <p>I want to be able to use USB battery as a power supply for an LED or something like that. So then a program would power it on and power it off making it flash. </p>
  
  <p>I know it sounds pointless but I need to do it for something awesome.</p>
  
  <p>I also know that it might require a custom driver.</p>
