A machine is running sid with a 2.4.20 kernel, and has some very power-hungry
USB devices plugged into it. The devices themselves don't have power
switches, but we'd really like to be able to turn them off and save power.
Why not just unplug them? We could, but the physical arrangement of the
machine, the devices in question, the other gear in the room, and the
pesky walls holding up the roof make the plugging/unplugging a hassle,
not to mention dangerous to the other gear (think stray elbows).
Is there a "power this USB device down and ignore it" command?
