I have had a Kobo Aura since 2015. And sometime in April I upgraded the firmware to the new 4.x series, currently 4.5.9587. I went a few weeks before adding any new books, but when I finally did, i started getting this error on "Send to Device"
Code:
calibre, version 3.7.0
ERROR: Error: Error communicating with device

I fussed with it for quite a while, going so far as to reset my Aura to factory setting, deleting all books and starting over but still I got the error - even on books I'd previously (before the firmware upgrade) loaded with no problem. Not on every book but most of them. I finally switched the Calibre driver back the "main" Kobo driver and no error. Books that would not load, did. So I switched back to the extended driver and I get the error. So whatever it is, it's something between the extended driver and the newer firmware on the Aura.
I watched here to see if anyone else would report it but I haven't seen it (or I missed it). So could it be something that I'm doing?
Thanks in advance for any help.
