This other method worked for me:

#!/bin/sh

list=$(udevadm info -e | grep -i -A 15 ID_INPUT_TOUCHPAD | grep -i "^E: DEVPATH" | cut -d'=' -f 2)
for item in $list; do
    subsystem=$(udevadm info -q all -p $item | grep -i "^E: SUBSYSTEM" | cut -d'=' -f 2)
    if [ $subsystem = "input" ] && [ -f "/sys/$item/device/inhibited" ]; then
       echo $1 > /sys/$item/device/inhibited
    fi
done
:

Now you can pass (0|1) as an argument in the command line:

# ./script 1 (disable)
# ./script 0 (enable)

Cheers,

Aitor.
