Device Communication Errors

SteveK · 11-11-2014, 05:20 PM

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
File "calibre_plugins.kobotouch_extended.device.driver" , line 280, in upload_books
File "site-packages\calibre\devices\kobo\driver.py", line 1906, in upload_books
File "calibre_plugins.kobotouch_extended.device.driver" , line 224, in _modify_epub
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.

The EPUB file is defective (not valid) in construction (container.xml)
Validate (and fix) the fie

As theducks said, it appears to be a broken epub. Fixing that should fix the problem. If it doesn't, can you post in the thread for the driver. That will get the attention of anyone who might want to look at it. Also, there is an option in the driver to "Silently Ignore Failed Conversions". This should allow the rest of the books to be sent and I think it sends the epub version of failed books.

As to going back to the standard driver, that is up to you. If you want to read books as kepubs, they need to be converted. The extended driver does this, or you can do a conversion using the kepub output plugin and send using the standard driver.

Davidfor - I'll certainly try the "Silently Ignore Failed Conversions". I'd rather one or two titles be completely ignored than a whole batch.

The strange thing is that I have received this error message, then the next attempt will succeed, despite the same titles being included. I've also found that sometimes I can individually transfer a book to my reader that failed when I attempted to send multiple titles. It would seem if the epub is broken that it would not work no matter what is attempted, but that is not the case.

At any rate, the ignore failed conversions option may take care of the problem.

Thanks for the recommendation!

I would expect the problem to happen each time with a particular book, but, it's possible it is caused by something else. It could be memory or a temporary file problem.

If the ignore errors option solves it well enough, that's good. But otherwise we need to do some debugging.
