OS Mojave cannot see Canoscan 8400f
iMac: MacOS 10.14 3Ghz Intel Core i5
Scanner: Canon Canoscan 8500f. The Image Capture app does not show the scanner does not show this in the device windows. Yet, using the Canoscan Toolbox X, all functions work correctly except the physical pushburttons on the device. I want to use this with ABBYY FInereader pro, but it also does not see the scanner. Canon states that there is "no driver" for this configuration.
