<div>I don't see evidence that the port is switched off.
This could just as easily be the device getting into a
state where it no longer talks to the USB, perhaps because
it was sent a command it does not understand. What does
`dmesg` say after the calibration is over?<br>

<div>Also, we are not the authors of colord-sane, that comes
with colord. Can you get it to show you some logging of
what it is doing? If you disable or uninstall it, does the
behavior change?</div>

<p>Here is what dmesg reports (the first tries are with `systemctl
stop colord.service`, the later with running `colord`):<br>
