I just upgraded Calibre to 0.8.26 and now I keep getting error reading device when I hook up my Kobo (original Kobo, not touch). On the 3rd, it dumped all of my books but they finally returned. I prefer adding my books with Calibre over Adobe Digital Editions but it looks like I can not use it. I plugged the Kobo in 3 different USB ports in case they were a problem.
