Unfortunately all the Visioneer scanners are unsupported in any
version of Linux so no point going on with this one :-( At least you
were given it so no loss in that respect but annoying all the same
when hardware doesn't work !!

FWIW - a lot of older scanners / printers etc bit the dust when WinXP
came out ( and mainly for the same reason - firmware that relied on
direct access to Windows API's ) so it's nothing new for hardware to
fall by the wayside.

"Price of progress" and all that !
