Comment 27 for bug 807832

Did you try the factory reset from the menus on the Kobo? I had a similar
problem a while ago, with an older version of Calibre and it worked
perfectly. I haven't had any trouble since.

Subject: [Bug 807832] Re: Error communicating with device - Kobo -

I just updated new software on Kobo and have the 8.34 version of
Calibre. I did a basic reset of Kobo. I lost some books from reader.
When I add a book it adds it 6 times. Some books I try to add do get
added at all. When I start Calibre it says it recognizes device, but
when I search device library nothing shows up. Any help would be
appreciated.

I get the following message:

calibre, version 0.8.34
ERROR: Error: Error communicating with device

Title:
  Error communicating with device - Kobo -

Status in calibre: e-book management:
  Fix Released

Bug description:
  I have the wireless Kobo and have been using Calibre almost since I
  first got it. I have just updated to the latest version (0.8.9) just
  in case that helps. My operating system's Windows 7

  Lately, my Kobo hasn't been processing new content. I reset it and
  tried again. Now I'm getting an error message in Calibre and even the
  pre-loaded books aren't showing up in the device tab.

  I tried deleting and loading the images folder and KoboReader.sqlite
  as that corrected someone elses problem, that looked like it might be
  similar.

  Here's the remainder of the error message:

  calibre, version 0.8.9
