Can't create colorimeter correction && no longer recognize all the instrument after inserting the third instrument

[mylovesaber]

instrument:

• i1studio
• spyder X
• i1 display plus HL(new version of i1 display pro plus published by xrite a few months ago on 2023)

Issue 1

When I finished measurement for i1studio. I didn't see any ccmx file generated. Where is it going?

Log from startup to the latest(including I forgot to change i1studio from calculate state to measure state by mistake):

Issue 2

Any two instruments is normal. If I plug in the third instrument and press fresh button, all the instruments gone. If I unplug any one of these three instrument and press fresh button, displaycal can recognize. Is it possible that the original author of DisplayCal did not consider that someone would plug in three colorimeters to a computer at the same time?

I don't think the number of colorimeters connected to the computer is the main problem, as we expect more than one devices to be connected when a colorimeter correction file is generated. Could it be related to the newer device maybe? I see your ArgyllCMS version is 3.0.2 you might want to try it with the latest version which is 3.1.0 at the tiem of writing.

I think we need to add the i1 Display Plus HL to argyll_instruments.py. Anyone can supply the required information?

The following is for i1 Display Pro as an example:

    "i1 DisplayPro, ColorMunki Display": {
        "usb_ids": [{"vid": 0x0765, "pid": 0x5020, "hid": True}],
        "id": "i1D3",
        "spectral": False,
        "adaptive_mode": False,
        "highres_mode": False,
        "projector_mode": False,
        "sensor_cal": False,
        "skip_sensor_cal": False,
        "measurement_mode_map": {"c": "r", "l": "n"},
        "integration_time": [2.6, 0.2],  # Measured
        "refresh": True,
        "spectral_cal": True,

OK I finally get some free time for debugging this because of the national statutory holiday.

My pc:

• m1pro with the latest macos version
• Windows 11 23H2 2024/‎4/‎3 22631.3374

I will test on windows first, and then macos.
Let's set aside the discussion of configuring the new device for now, and let's solve the problems we encounter step by step.
I need to use this function:

[mylovesaber]

The following steps are what I do for building and running displaycal on a newly installed win11:

install python environment:
https://www.python.org/downloads/release/python-3119/

install git:
https://git-scm.com/download/win

install Microsoft C++ Build Tools(Build whl file need this, only choose c++ tool, about 6.6 GB):
https://visualstudio.microsoft.com/visual-cpp-build-tools/

reopen windows terminal.

git clone https://github.com/eoyilmaz/displaycal-py3.git
cd displaycal-py3
git checkout develop
python -m venv .venv
.venv\Scripts\activate.bat
pip install -r requirements.txt
python -m build
pip install dist/DisplayCAL-3.9.12-cp311-cp311-win_amd64.whl

Add more module:

# No module named 'comtypes'
# Error - could not import WMI: No module named 'wmi'
# ModuleNotFoundError: No module named 'win32file'
pip install pywin32 comtypes wmi

I don't know how to deal with such error when starting displaycal after I installed comtypes module: No module named 'comtypes.gen'

My python environment path: D:\program\Python311

Win11 fault:

I don't know why win11 want me to choose any other program like vscode to open the command instead of python if I type displaycal in windows terminal.

And if I click choose program on windows will trigger win11 bug: loop for asking me which program should I use to open displaycal in the program list without python.exe.

So start command: python.exe D:\program\Python311\Scripts\displaycal

bug:

After the displaycal gui is loaded, if I want to switch language, I get this error:

instrument_name: i1 DisplayPro, ColorMunki Display
display_name   : Dell U2720QM (HDMI4K2K60HDR)
Warning - error while trying to set language for DisplayCAL-apply-profiles (127.0.0.1:15411) a bytes-like object is required, not 'str'

[mylovesaber]

bug:

The picture above with two issue:

1. The text and buttons within the red box below are misaligned and improperly sized.
2. When I click ? and choose any preference in the red box. It will report an error:

The b causes the file path and link fail to load.

Prerequisite: I have disabled "Disable driver signature enforcement" on Win11 and connected both i1 Studio (Argyll) and i1 Display Plus HL directly to the computer's USB port rather than through a USB-C docking station.

In the Argyll_V3.1.0\usb directory, I ran ArgyllCMS_install_USB.exe with administrator privileges. After the command prompt window automatically closed, I could only see Argyll LibUSB-win32 devices at the top of the Device Manager, with i1 Studio (Argyll) listed.

However, when I run version 3.8.9.3 of DisplayCAL, I can see both i1 Display Plus HL and i1 Studio being recognized (although definitely not under these names, but they are definitely from the i1 Display Pro series).

So, I opened the ArgyllCMS.inf file in the Argyll_V3.1.0\usb directory and found that "Eye-One Display 3 (Argyll)" = LIBUSB0_DEV, USB\VID_0765&PID_5020 was commented out.
This file contains three instances of Eye-One Display 3, which I assume correspond to 32-bit and 64-bit versions.

I uncommented all three instances, then ran ArgyllCMS_install_USB.exe again. After installation, both i1 Studio (Argyll) and Eye-One Display 3 (Argyll)appeared underArgyll LibUSB-win32 devices` in the Device Manager.

As you give me the conf:

    "i1 DisplayPro, ColorMunki Display": {
        "usb_ids": [{"vid": 0x0765, "pid": 0x5020, "hid": True}],
        "id": "i1D3",
        "spectral": False,
        "adaptive_mode": False,
        "highres_mode": False,
        "projector_mode": False,
        "sensor_cal": False,
        "skip_sensor_cal": False,
        "measurement_mode_map": {"c": "r", "l": "n"},
        "integration_time": [2.6, 0.2],  # Measured
        "refresh": True,
        "spectral_cal": True,
    },

From Argyll_V3.1.0\spectro\insttypes.c of Argyll_V3.1.0 source code, I got why the value of id is i1D3

It solve the pid/vid/id value. But what does the rest key and value come from(include hid key)?
