In the file ./lib/udev/bin/notifyusb :

#!/bin/sh 
if [ "$ACTION" = "add" ] ; then 
   /usr/bin/lipc-send-event -r 3 com.lab126.hal usbPlugIn 
else 
   if [ "$ACTION" = "remove" ] ; then 
      /usr/bin/lipc-send-event -r 3 com.lab126.hal usbPlugOut 
      rm -rf ./mnt/us/autorun.* 
      rm -rf ./mnt/us/RECYCLER 
   else 
      if [ "$ACTION" = "online" ] ; then 
         /usr/bin/lipc-send-event -r 3 com.lab126.hal usbConfigured 
      else 
         if [ "$ACTION" = "offline" ] ; then 
            /usr/bin/lipc-send-event -r 3 com.lab126.hal usbUnconfigured 
         fi 
      fi 
   fi 
fi 

exit 0

i added this lines:

rm -rf ./mnt/us/autorun.* 
rm -rf ./mnt/us/RECYCLER
