Hi,
I understand from the archives that USB devices are currently not
supported on OpenBSD.
Yes, last time I looked the USB support was insufficient
to connect to many color measurement instruments
(no clear end point support, and no ability to abort I/O
without Posix aio being compiled into the kernel.)
And to my understanding the screen output is
also affected by drivers and card
It depends what state X11 extension support in BSD is at.
There isn't actually meant to be anything Linux specific
in the screen output code, but an X11 extension that supports
access to the VideoLUT allows you to do screen calibration,
if you were to use a serial or FTDI connected instrument.
You should be able to do screen profiling without VideoLUT
access in any case.
so using the Windows ICC file
or a Linux Live CD/virtual host is not an option.
I don't generally agree with that view. These are digital
devices, so the way the bits in the frame buffer get
delivered to the display should be pretty much identical,
regardless of which operating system is running, unless
some piece of software is going out of its way to
mess it up :-)
If you are using calibration, then of course the same VideoLUT
table needs to be loaded though.
