I have been having difficulty lately when I attempt to copy titles from my Calibre library on my computer to my Kobo Glo, as I have been receiving periodic and random error messages indicating "Error Communicating with device". The "details" from the last time it happened are copied below:

calibre, version 2.9.0
ERROR: Error: Error communicating with device

Failed to parse 'Harry Bosch Novels, The: Volume 2: The Last Coyote, Trunk Music, Angels Flight' by 'Michael Connelly' with error: '' (file: calibre_plugins.kobotouch_extended.container, line: 179)

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 87, in run
File "site-packages\calibre\gui2\device.py", line 583, in _upload_books

InvalidEPub: Failed to parse 'Harry Bosch Novels, The: Volume 2: The Last Coyote, Trunk Music, Angels Flight' by 'Michael Connelly' with error: '' (file: calibre_plugins.kobotouch_extended.container, line: 179)

If I read the log correctly, the problem seems to be with line 179 of the "kobotouch_extended" plugin. If this happens when I've selected multiple titles to transfer, none of the titles successfully transfer. The next time I try it, it may work without a glitch. I've tried different USB ports and different USB cables, so I don't believe it is a hardware problem.

What might be causing this problem? Do I need a different plugin, or would I be better off using the regular plug-in rather than the extended plug-in?

Needless to say, this problem is frustrating and greatly increases the transfer time due to multiple attempts, so any recommendations you provide will be most appreciated.

Thanks.
