Ok you speak about the Lprof project which is, since a while, different 
from lcms. The original author, Marti Maria, does not any longer work on 
the open source version of this application. While lcms is continued by 
him. Lcms is a CMM and includes some commandline utils. It is used for 
instance in Scribus and CinePaint for theyre colour rendering and

These are the serial ones like Spektroline/-scan, DTP 92, DTP 41 ...
For USB devices are no drivers downloadable. But you can ask the 
manufacturers and hopefully GMB/Xrite will make them available.

To create profiles you can use Lprof and the commandline profiler Argyll. 
No foss applications, that I am aware of, have jet started to edit 
profiles for inside use.
