Don't know what this means for the 1200 DPI model, but the state of affairs concerning the ScanExpress A3 600 is that there is a Mustek driver here:

These are RPMs (i386) including a customized mustek_usb2 driver (libsane 1.0.19). It was impossible for me to get these drivers running (suspected to
be quick'n'dirty) and also I would like to run other scanners in addition. I've written several time to Mustek to give free the source of their
mustek_usb2 with no reply at all.

Maybe it's a good idea to keep on with the enquiries to give away their source, BTW it has been discussed before on the list
(http://lists.alioth.debian.org/pipermail/sane-devel/2008-August/022583.html) that their driver packet injures the GPL of Sane.

Another way would be naturally to make a driver on our own, begin with a USB sniff within Windows and to manipulate mustek_usb2 to begin with. But I
do not have any experiences with that.
