Some USB hubs have the ability to turn power off to its downstream devices.

"Is it possible to power up ports on a USB hub from Ubuntu?" https://askubuntu.com/questions/149242/is-it-possible-to-power-up-ports-on-a-usb-hub-from-ubuntu Which points to some c source for hub-ctrl.c

I tested this on Ubuntu with a Dream-Cheeky USB LED unit, and it did seem to turn the power off - although when turned on again, the device had remembered (!) its LED on/off state ??? - This did not happen when I unplugged and repluged the USB lead to the LED...

It looks like someone has looked at compiling this for Windows, but I could not find the result, sorry.
