I imagine something like a harddisk might use more power while reading/writing than when it is just spinning. It might even start powered down until sent some command that causes it to spin up. A scanner certainly uses more power with the scanner light on than with it off, and it starts out off until it is in use on most scanners. Of course I have never seen a usb powered scanner, so it doesn't seem to matter.
