Handheld scanners will generally require a kernel-module, as most of them
are using a proprietary Interface card. I am unsure, if the generic
Mustec handheld scanner driver will be able to handle the newer (color)
models, but here is a pointer for what to search :

Developer Email Driver name
Thomas Faehnle Thomas.Faehnle@student.uni-ulm.de (m105)

This driver should be found on any major Linux-site, probably best on sunsite.

If the above driver doesn't work, it will probably be a good place to start
from. It conforms to the Linux handscanner IOCTL interface standard which
should be enough to describe these types of scanners.

SANE support will be done using a LHIIS-to-SANE-bridge when I come around
to it. This won't be hard, as the basic design idea behind LHIIS is the
same as the one behind SANE (though the latter has a much improved
implementation).

;-) - the old story ... just like VESA - though VESA is a lot better ;-)

See above ...
