The enclosure is powered by the USB cable, and you are right, one of the
laptops cannot spin up the drive. But the USB cable has two plugs on it
where it connects to the PC, so you can get power from 2 USB ports
simultaneously. I have tried it on both desktop and and laptop units and
the drive does spin up OK so I don't think power supply is the problem.

I'm currently looking in to the cable select pin on the drive (pin 28) as I
think that might be the cause of the problems.
