Could, arguably should -- but doesn't, just now. I don't think I'd try to manage all system devices' power through sysfs from usermode yet ... :) I'm soon to rip out the recursive stuff in USB, where USB does the recursion for "echo -n 3 > hub/power/state" commands. That's just getting in the way, and I never did think such functionality was specific to USB anyway. - Dave
