You can use a much simpler script for embedded work that can cope with 
firmware loading then the hotplug or udev packages would use.

#!/bin/sh
# Both $DEVPATH and $FIRMWARE are already provided in the environment.

HOTPLUG_FW_DIR=/lib/firmware

if [ "$ACTION" = "remove" ] ; then
  echo "(aborting as it is remove)">>/tmp/hotplug_debug
  exit 0
fi

sleep 1
echo -n "1">/sys/$DEVPATH/loading
sleep 1
cat $HOTPLUG_FW_DIR/$FIRMWARE >/sys/$DEVPATH/data
