Failure in communication with Kobo Aura (1st edition)

[Jan Korteweg]

Hello,
Since Callibre's last update it fails to communicate with my Kobo Aura (1st edition), that is, it doesn't show the content of my Kobo's memory. Does anyone know why? I have activated the plugin voor my reader and the Kobo is not listed among ignored readers.

calibre, version 5.35.0
