title: Turn off power to USB Port programmatically
body: <p>I have a project that I'm working on and I want to use these:
  <a href="http://www.woot.com/blog/post/usb-powered-woot-off-lights-2" rel="noreferrer">http://www.woot.com/blog/post/usb-powered-woot-off-lights-2</a></p>
  
  <p>However it looks like they just have on/off switches. They aren't something that you can interface with programmatically.</p>
  
  <p>So I was thinking, if I could find a way to cut the power to the USB port, that would allow me to turn the lights on and off with my app. However I cant find any way to cut the power to the USB port. Is this possible?</p>
