Those documents and files are downloadable also from   www.upek.com
They are rather scattered out there, but still...

In Linux environment we do need to define and implement our own
interface to the the device.  There is  BioAPI (www.bioapi.org)
interface specification, but that is rather high up in the application
stack.  (There exists also NIST written Linux version at that site,
and it seems to be "BSD with advertisement clause" licensed...)

My reading so far seems to indicate, that this is mostly doable
in the application space without needing kernel space drivers.

Implementing BioAPI interface library with device specific backends
(much in the same manner as SANE works) is the way, I do think.
To how large an extent the existing source code can be used
in this is so far unknown.

To be able to do the device specific backends, I do need to have
the detailed USB interface protocol descriptions, not just a windows
library binary wrapping them up into BioAPI.   I can handle NDA 
documents as long as the resulting source code into Linux (and any
other UNIX-like system capable to use it) can be published.
