Hello everyone, in my case.
I need to go to the services tab in the Task Manager and have the logi_lamparray_service turn off.
After that, my i1 display plus can be connected normally.

It seems Windows Dynamic Lighting is behind a lot of the issues with HID controlled devices, such as the i1D3 probe.
Third party software and services that are linked to Windows Dynamic Lighting, such as Logitech LampArray Services do seem to suggest such implementations are at best faulty, and possibly just exceptionally poor software.

It also appears that Windows updates are now installing some of this disruptive software/services by default...

I'm having problems connecting an OEM i1D3 probe to my Colourspace HTP install.
I purchased a Lenovo Thinkpad to be a dedicated Colourspace calibration machine, nothing installed other than a minimal configuration Windows 11 Pro install and ColourSpace HTP. When trying to connect to the probe I see 'ERROR' message.
The device shows as a HID device in 'Device Manager', and an i1Display3 in 'Devices and Printers'.
Am I required to install some a device driver or are they 'built-in' to ColourSpace? Given all the talk about incompatible drivers here I'm wary of randomly installing software trying to fix this.

Please see the information in this thread above.
There is nothing you need to install, but likely things you need to uninstall or stop running.
(Although you haven't specified exactly which i1D3 you have?)
