Thanks for the reply Graeme.

I'll assume you mean the relevant bits regarding the
comm port? If so:
1 = 'usb:/bus0/dev0 (Xrite DTP94)'
2 = '/dev/ttyS0'
3 = '/dev/ttyS1'
4 = '/dev/ttyS2'
5 = '/dev/ttyS3'

Yes, I have followed the setup instructions for devsub
at the bottom.

If I understand the rules mods I followed referenced
above, then I don't think what I am seeing is correct:
mdufresne@wallace:/usr/local/argyll/bin$ ls -l
/dev/bus/usb/002
total 0
crw-rw-r-- 1 root root 189, 128 2006-10-31 19:25 001
crw-rw-r-- 1 root root 189, 129 2006-10-31 19:25 002
crw-rw-r-- 1 root root 189, 130 2006-10-31 19:25 003
crw-rw-r-- 1 root root 189, 132 2006-11-02 18:25 005
Manually chmodding the files has the desired result:
mdufresne@wallace:/usr/local/argyll/bin$ sudo chmod
666 /dev/bus/usb/002/*
Password:
mdufresne@wallace:/usr/local/argyll/bin$ ls -l
/dev/bus/usb/002
total 0
crw-rw-rw- 1 root root 189, 128 2006-10-31 19:25 001
crw-rw-rw- 1 root root 189, 129 2006-10-31 19:25 002
crw-rw-rw- 1 root root 189, 130 2006-10-31 19:25 003

The instrument can be removed from the dark surface.
Place instrument on test window.
Hit Esc to give up, any other key to continue:
