This morning /dev/DC10plus was pointing to hdd - a DVD drive.  After running 
udevtrigger manually it pointed to ram3.  Running it again made it point to 
ram14.  This seems very random.  I'll look at udevinfo again and see whether 
I can add further identifying lines.  I'll report back whether that makes any 
difference.
