It Always stop on the step “Profiling” and notice “dispread: Error – dispd->read returned error code 2” I almost turned mad !!:( It Appear Not less than four times , I Waste a lot of time on this . (very low probability stop on step “calibration”)
Already Disable “Allow skipping of spectrometer self-calibration” option and “”highres“ and”adaptive “ mode
Already use USB2.0 hub and tries several ports
System environment ：displaycal 3.2 with Argyll_V1.9.2 x64 (newest version) , windows10 and not install other conflict software
however ， the ColorMunki photo works well on my mac.

Hi,
Communication problem is usually related to faulty/buggy USB. Error code 2 is instrument access failed which is to be expected after unexpected USB communications breakdown. There really isn’t anything I can do to help fix this because it’s probably hardware related.
This fits the picture, i.e. the Mac USB (as well as the instrument itself) seems to be fine, but it is probably unlikely you’ll have much luck on the other machine. You can try to reduce the total number of patches (e.g. below 500) as it seems the USB comms only goes out of whack after a while.
