UPDATE!

I just discovered that not all devices create a "product" file when inserted, 
so I've changed the script to look for a symbolic link to the device driver. 
AFAIK, an unknown device will not have this link (please correct me if I am wrong).

---- SNIP ----

#!/bin/sh

BASE="/sys/devices/platform/at91_ohci/usb1/1-1/1-1:1.0"

indicated=0
while [ 1 ]; do
     sleep 1
     if [ $indicated == 0 ]; then
         if [ -d "$BASE" ]; then
             indicated=1
             if [ -h "$BASE/driver" ]; then
                 logger "A known USB device has been inserted."
             else
                 logger "An unknown USB device has been inserted."
             fi
         fi
     else
         if [ ! -d "$BASE" ]; then
             indicated=0
         fi
     fi
done
