[argyllcms] Re: dispcal 1.0.0 doesn't like me

Okay, so it's been a little while longer for me to reply than I expected. Life happens....
Anyway, short version: it's somewhere in the ``read a display instead of something reflective'' code (and still in v1.0.1). Without arguments, spotread works fine, but spotread -d has the same problem as dispcal. Perhaps it's the worng initialization string being sent to the i1? Not that I'd know how to know. 

Details below:

Only because it was complaining that it couldn't communicate with the i1 -- I wanted to see if it couldn't talk to it at all or if it was specific to the attempt to calibrate it. 

OK, I was just wondering if this was part of what triggers the
problem, or whether it was incidental. I'm gathering that it is
incidental.


Yes, just incidental. It happens after the failure.


Are you running through a USB hub ?
This is through the keyboard -- but beta 7 works fine like this. I'll try plugged directly into the computer later today. 

See if that makes any difference.


No difference.


Does it fail every time, and at the same point ?


Yes, and yes. Exactly identical every time.


Was your machine under heavy load (ie. running some other
CPU or I/O intensive task) ?
Absolutely idle except for Argyll. Plus, it's a 2.8 GHz Core 2 Duo with 4 Gbytes RAM, so it should take an awful lot to load it up. 


What does the trace from V0.70B8 look like ?
