This sounds promising. 

I'll give this a try tomorrow on a RaspberryPi:

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,
