I've got this scanner. It's USB powered, and the docs say it's max power
draw is 5W (which I'm assuming is 1A @ 5V)
I'm looking to drive that with something tiny runnig SANE that I can bolt
under the desk (I was a full-on Linux server, but it died and requirements
have changed) so was looking at a Raspberry Pi 3. I've seen in a couple of
places that the USB line can provide 1.2A which is shared across the 4 USB
Also based of  looks like I'd also need a 2.5A power supply to make the
whole thing work.
So, have a I got my sums right and more importantly, has anyone here tried
it in practice?
