A Lexar reader of some sort had a driver written that was very similar
to the jumpshot CF reader driver that I modified to get working a
month or two ago. Start following links from here to see if its what
you need:

(Lexar's are not Datafab Jumpshot chips, but the drivers have the same
author)
Your device looks a bit more capable that the one the driver I'm
thinking of was for (so it may be a different chipset), but its worth
a look.
good luck,
Greg
