On my Feisty router Dell PIII-1ghz with custom 2.6.22 kernel, the following commands appear to work based on suggestions from PowerTOP 1.8: I've added them to my /etc/init.d/rc.local.

echo 10 >/sys/bus/usb/devices/usb1/power/autosuspend
echo auto >/sys/bus/usb/devices/usb1/power/level

The commands are modified from a thread I found on the USB autosuspend (which were posted as commands to use with a .23 kernel).
