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.
