scanner support vista 64

Hi,
I need to support a GL842 based scanner on vista 64.
Scanner is currently supported on 32 bit systems via TWAIN.
Scanner has satellite apps for imaging (32 bit), which are highly coupled to
driver and it's TWAIN DS.
I saw that there is no TWAIN DSM (or will ever) be available for vista 64.
What is the quickest path to support the device (and satellite apps)?

1. Can I get by with INF manipulations and the (potentially revised) 32 bit
driver?
2. If not: Must I implement a 64 bit driver for the scanner?
3. If yes: can I get by with STI (or full WIA required)?

The way I see it, I am pretty much headed for a new 64 bit STI driver to
host my 32 bit TWAIN DS....
Am I right?
Shlomi
BTW
This Q may as well goto a 64 bit group... started here.

I have had the same problem with 64b trying to use a scanner
I solved my problem by running the scanner off a usb 1.1 hub
The data has a timing issue and the hub slows down the dat
going thru the hub so the scanner will work
I hope this helps
