    Looking for any useful suggestions.

    Windows 11, disrpd err 32 attempting to access i1Display.

    Works if I reboot and start DisplayCAL quickly. If I wait too long then nothing but another reboot will fix it.

    Tried two different methods to find another application using USB device – all failed. None of the known applications that affect USB devices are installed.

    Tried multiple USB ports.

    Today, I faced this error and managed to solve it, although it took me way longer than expected. This error occurs when another process is accessing the colorimeter. It can be any kind of program or driver. In my case, it was Logitech’s “logi_lamparray_service.exe.” I disabled this service, and now it’s working like a charm.

    Thanks. Like I said I tried two methods to find another process that uses the device and neither worked. I guess I’ll start looking through services for anything suspicious.

    I recommend using Autoruns (from Microsoft), which will make disabling startup processes easier. Keep in mind that you have to reboot after disabling a startup process.

    I am having the same issue David C, did you find the culprit?

    I have an almost fresh install of windows, so not many things installed, and yet I don’t find the reason why this is not working.

    No, I haven’t had time to even look yet.

    Mine started on a new machine with Windows 11. It is sold as a “game machine” and has lights. I use the driver because I haven’t physically disabled them yet and otherwise they flash around. That’s the first thing I’m going to try because I’ve found others who say the lights on their machine were the culprit.

    Thank you! The Logitech service apparently got installed with one of the GHub updates (or so it seems, anyway) and I had no idea why DisplayCal suddenly stopped working for me out of nowhere.
