Hi,
my Kobo Aura HD eReader no longer opens in Calibre. I have Calibre version 4.23. Tried reboots Calibre, device, nothing changes. I reactivated the Kobo plugin for Aura, nothing either. Calibre does not detect my device. And yet, I had no problem before. Can anyone help me find a solution? I'm afraid I won't be able to put books in my Kobo anymore.
