How to run rmmod ehci-hcd when the screensaver? And when you turn off the screensaver run moprobe ehci-hcd?

This command will block script until screensaver will be enabled:

lipc-wait-event com.lab126.powerd goingToScreenSaver

This command will block script until screensaver will be disabled:

lipc-wait-event com.lab126.powerd outOfScreenSaver

Here is a script (replace echo with modprobe/rmmod):

lipc-wait-event -m com.lab126.powerd goingToScreenSaver,outOfScreenSaver |  while read event wtf_num; do
  if [ "x$event" = "xgoingToScreenSaver" ]; then
    echo "screensaver enabled"
  else if [ "x$event" = "xoutOfScreenSaver" ]; then
    echo "screensaver disabled"
  fi; fi
done
