Output voltage of a USB port is _always_ 5VDC

Output voltage of a USB port is _always_ 5VDC
it can be modulated with zero voltage, like PWM

This sounds promising.
I'll give this a try tomorrow on a RaspberryPi:
http://stackoverflow.com/questions/4702216/controlling-a-usb-power-supply-on... There are many threads saying that power in usb ports seem to be hardwired and not controlled by software.
I suppose, if this doesn't work I could potentially use PWM with the analog pins of the Pi and Miller's external?
best,
