Hi,
I have a raspberry pi, and I want to use it to controll an usb ventilator ( I have my reasons for it
).

As far as I understand it, it has no driver but just starts when it gets power.
I have read you can't disable the usb power lines on the raspberry pi, just the data lines. And that you can use an USB hub to archieve it, but I am not sure if the HUB is strong enough to power the ventilator (5V, 500 ma). The standard says USB Bus powered hub must not power Highpower devices but I am not sure if the manufacturers obey the standard.
Would the Pandora be able to power its usb power lines down? So the ventilator would stop and start if I like it? If yes, are there still cheap broken Pandoras (i need no screen, just somesthing the starts a ventilator via scripts)?
