Hi All,
I hope that you can help me. I have two Kobo readers (Glo HD and Aura). Both used to work perfectly with Calibre, but since a few weeks they are not being recognized anymore.
I'm running Win 10 with Calibre ver. 2.49 and Kobo firmware ver. 3.16.576. Both readers are correctly recognized in Windows (drive letter assigned) and by the Kobo App.

Thanks!
Bart
