I have a similar issue re the LiDE 30.. this is what Canon USA told me..
Dear Mike Hall:
Thank you for writing back to us regarding your LiDE 30.
Globally, Canon is comprised of many different sales divisions. Each sales
division makes their own business decisions as to the products and features
they feel will help them achieve their goals and best suit their market.
Canon USA has made the decision not to include the WIA driver for older
scanners sold in this market.
We apologize for any inconvenience this may cause.
Please let us know if we can be of any further assistance with your LiDE 30.
Thank you for choosing Canon.
