# This script changes the permissions and ownership of a USB device under
# /proc/bus/usb to grant access to this device to users in the scanner group.
#
# Ownership is set to root:scanner, permissions are set to 0660.
#
# Arguments :
# -----------
# ACTION=[add|remove]
# DEVICE=/proc/bus/usb/BBB/DDD
# TYPE=usb

if [ "$ACTION" = "add" -a "$TYPE" = "usb" ]; then
  chown root:scanner "$DEVICE"
  chmod 0660 "$DEVICE"
fi


# That's an insecure but simple alternative
# Everyone has access to the scanner

# if [ "$ACTION" = "add" -a "$TYPE" = "usb" ]; then
#  chmod 0666 "$DEVICE"
# fi
