I have exactly the same problem as Harris, windows won't find the driver. It doesn't look like or automatically replace the old .INF (when copied and pasted) either.
EDIT: you must get rid of the .txt extension of the file as the type is .txt. It has to be of the INF type. If you can't see the extension follow this for example: http://quehow.com/how-to-change-a-file- ... /4450.html
