Question : Problem: Software Controlled Power Bar

I am trying to find a power bar that I can turn off and on via software.  I know there are power bars that I can telnet into and control via a network connection, but I am really looking for something that is USB.  Ideally it would be programmable/come with some sort of component that I can use to communicate with the power bar.
