If you are a member of colord, you should then be able to open it.
Graeme, thank you for your prompt reply.
I have read, carefully I hope,
http://www.argyllcms.com/doc/Installing_Linux.html.
Here is what happens:
$ ls -la /etc/udev/rules.d/55-Argyll.rules
-rw-r--r-- 1 root root 5675 2015-12-13 12:17 /etc/udev/rules.d/55-Argyll.rules
# groupadd -r colord
# usermod -a -G colord <user>
# ls -lR /dev/bus/usb
...
/dev/bus/usb/008:

crw-rw-r-- 1 root root 189, 896 2015-12-14 05:55 001
crw-rw-r-- 1 root root 189, 897 2015-12-14 05:55 002
Then plugin the instrument, and
# ls -lR /dev/bus/usb
...
/dev/bus/usb/008:
total 0
crw-rw-r-- 1 root root 189, 896 2015-12-14 05:55 001
crw-rw-r-- 1 root root 189, 897 2015-12-14 05:55 002
crw-rw-r-- 1 root root 189, 904 2015-12-14 16:34 009
The instrument is not owned by group colord. And yet,
$ spotread -?
...
-c listno Set communication port from the following list (default 1)
1 = '/dev/bus/usb/008/009 (X-Rite i1 DisplayPro, ColorMunki
Display)'
But if I install the package of colord, and
# ls -lR /dev/bus/usb
...
/dev/bus/usb/008:
total 0
crw-rw-r-- 1 root root 189, 896 2015-12-14 05:55 001
crw-rw-r-- 1 root root 189, 897 2015-12-14 05:55 002
crw-rw-r-- 1 root colord 189, 905 2015-12-14 16:44 010
I have tried editing 55-Argyll.rules to change colord to another group,
but it had no effect.
For now I'll keep installing and removing colord :-)
