I assume you are talking about an external piece of equipment, not a
USB hub etc. Some pieces of equipment have USB interfaces, but I
suspect many can not turn themselves on and off in response to a USB
command. Macs can, but that may be rare. Even so it would be worth
checking the manual. Otherwise you may have to look at USB-controlled
solenoid drivers. You'll need software too, but some like http://www.phidgets.com/
do have Mac drivers.

Hey,
I have a Cocoa application that controls an external USB device. I
want to be able to turn the device off when the user performs some
action, like click a button. Is there a way in Cocoa or IOKit to
disable power to a USB Socket? The application runs on Leopard.
Thanks in advance,
Omar Qazi
