I had a look in /var/lib/usbutils/usb.ids to figure out what the ID is
registered for.  As far as I can tell it is not connected to any 
USB device in the USB ID database.  Perhaps it is a good idea to get
both IDs registered there?  The ID in question is supposed to be the NXT
in 'flash mode'.  Not quite sure when that happen and if it is supposed
to have a unique ID in that mode.
Happy hacking
