The X-Rite software supports using the Huey to make periodic changes to the
calibration and/or CM setup as the lighting conditions change. So this is
only useful on Windows and OS/X machines if you use the X-Rite supplied
software.

udev is your friend here. Look it up in the Argyll docs.

No there needs to be a USB connection to the computer either directly to a
computer USB port or through a USB HUB like the one on the monitor to one of
the computer USB ports.

Also the Huey can be affected by bright lights during measurements since it
does not do as good of a job of blocking off ambient light as other meters.
So be sure to keep any direct light off of the screen during this process and
if possible use it in a dark room.
