Error – new_disprd() failed with 'Instrument Access Failed'

[EveryDayIsADayDream]

Hi,

I have a problem with DisplayCAL using ColorMunki Display (DisplayCAL v3.3.5.0 and Argyll 1.9.2). I’ve tried all USB ports (2.0 and 3.0) from I/O panel and front. X-rite software is working fine but obviously I don’t have even installed it on PC. Tried clean Windows 10 x64 few times and it works but not for long and I need to use PC for more things than only clean install and calibration. Tried with Argyll USB drivers and without it, running as administrator and all the things which I found in internet but maybe it’s somethins missing. I hope someone can help in that situation.

There is always same error on calibration:

Updated Argyll version to 2.0.0, changed motherboard in my pc, still not fixed, can’t solve that problem.

Hi,

I had exactly the same problem and resolved it by changing the usb driver used by the ColorMunki to the libusb one as described here:

How to install your spectrophotometer on Windows to work with Coloris or ArgyllCMS

It did mean that the ColorMunki/X-rite software stopped working and I haven’t tried swapping drivers back as I do not see the point given that I now have a working system.
