Yeah, unfortunately you are stck with the software scanner controls of the V45, which doesn't utilize the 9110 to the max.
I set up a dual boot on my machine so I still have my XP based office as well as 7. Although you aren't supposed to be able to, if you have two drives you can do this actually installing the XP second, but it's tricky; you can mess up your 7 install if you don't take certain precautions. Let me know if you want a walk through :-)
