New user, eye-one display 2, DisplayCAL: Waiting for send buffer

[zougloub]

I discovered I had an eye-one display 2 lying around and decided to use it today with displaycal-py3, which I never used before (but I'm very familiar with color and have used argyll for cameras and scanners).

When opening the software the colorimeter is detected, and it can detect that luma variation is tiny when I leave it not on the screen, and when I put it on the screen a first batch of measurements is done, then at some point the software is hung with "DisplayCAL: Waiting for send buffer".

Command line:
  /usr/bin/argyll-dispcal
    -v2
    -d1
    -c1
    -yl
    -P0.5,0.5,1.5
    -qm
    -t
    -g2.2
    -f1.0
    -k0.06
    -A4.0
    'Monitor 1 2024-04-02 6% neutral 2.2 M-S LabLUT'

can you please try it with DisplayCAL 3.9.12 and ArgyllCMS 3.2.0 again.

I tried on last wednesday with the develop branch, and was successful. So, whatever changes you did in the past 2 weeks fixed it for me :)

Closing this as per @simonszu 's comment.
