title: Linux USB: turning the power on and off?
body: <p>How can I programmatically enable and disable the power to a particular USB port on Linux? Is such a thing even possible? Mac answers appreciated as well!</p>
  
  <p>I was trying for a <a href="https://en.wikipedia.org/wiki/Woot#Special_events" rel="nofollow noreferrer">BOC</a> (don't pretend you weren't try to get one too!) and ended up with one of these, and would like to get some use out of the thing by hooking it up to our server monitor.</p>
