I'm getting the same kind of error with my ColorMunki on OS X 10.6.6 using ArgyllCMS V1.3.2 . . . . chartread: Error - Configuring USB port 'usb:/bus29/dev4/ (X-Rite ColorMunki)' to 1 failed with -4 (No such device (it may have been disconnected)) You mention driver work around for the ColorMunki. Is there something I need to do on my system to take advantage of this, or do I perhaps have another issue? I notice that an applet is running in the toolbar at the top of the screen, ColorMunki Photo Tray 1.1.0. Terry.
