debianized Scanner support somewhere?

[Thomas Adams]

Is it possible to get a deb File which provides support for a scanner? I'd
be most interested in support for the Logitech ScanMan32 Mac which is a
handscanner which operates via a little box with a SCSI connector at one
end and the handscanner jack at the other. Shouldn't be too hard to support
this should it? IF there is no such driver, how would I write one myself?
I.E. what should I read, would it be better to disassemble the Mac driver
or snoop the SCSI bus or what?
