It would be an easy way to prevent placing an > overload on the USB power bus. That'd only be needed if it was engineered by a fool. If you were building a box to be externally powered, you wouldn't design the circuitry so that it tried to power the drive from the USB cable, as well. You'd only power as much as was needed directly from the USB port (e.g. part of the USB interface). -- Don't send private replies to my address, the mailbox is ignored.
