  1. I run DisplayCAL 3.2.2 + Argyllcms 1.9.2 on Arch Linux. When I ry to calibrate a monitor using Colorhug (firmware 1.2.3) I get the error:

    Error – new_disprd failed with ‘Instrument Access Failed’

    I tried the two USB 3.0 ports of my notebook. I get the same errors regardless of the USB port used.

    1. Check in menu Tools -> Instrument -> Install Argyll CMS instrument configuration files. If this menu item is grayed, the necessary files are already installed, though, so the problem then lies elsewhere.
