WEll, Sir With all the detailed information You've presented here, Neither can I.
You need to do more than say my computer can't recognize what looks like a misspelled name and expect a good answer.
Have you tried here?:http://e-gizmo.com/wordpress/?p=369
it seems to be one place to go for information on
a copy of an early Arduino board made in 2009 called a "Duemilanove" Your computer doesn't recognize the board because
the usb driver isn't properly installed and I don't know enough of the board or your computer to advise you on it's proper installation.
I would suggest you ask on the e-gizmo blog page that i mentioned above.
