I can see the scanner from my unprivileged user, and it shows up the the
GNOME hardware/calibration dialog. Unfortunately, clicking on the
"calibrate" button does nothing. On Debian buster with GNOME 3.30, doing
so brings up a calibration wizard.
I believe that I have determined why this is so. There is needed software
which is not yet packaged for Guix. The calibration wizard is provided by
gnome-color-manager [0]. Gnome-color-manager depends on argyllcms [1],
which is also not yet packaged. Argyllcms in turn requires the Jam build
tool [2][3] or the Jam fork by FreeType, ftjam [4]. Jam is also not yet
packaged. As a little twist for Jam, it looks like Perforce upstream
stopped developing it in 2014, and the FreeType fork's latest release
seems even older. It is still available in modern Debian, so hopefully
this won't be too much of hurdle.
