No need to stop/start hotplug. At least for usb.
If nothing is pugged in it works just fine. And anything else just asks
for trouble. Especially mounted storage devices.
And suspending is a lot faster without it.
I actually have a script that prevents suspend when it can't unmount all
external devices.

Oh and afaik /proc/acpi/sleep is depreciated. /sys/power/state should be
used:
echo -n "mem" > /sys/power/state
