There shouldn't be any difference between calibre 2.7 and 2.8. Can you uncheck the attempt to support newer firmware version and post the full error message? That will tell me what the driver is seeing on the device.

Ok -- upgraded to 2.8 and de-selected the option. Upon connecting the device I get the following:

calibre, version 2.8.0
ERROR: Error: Error communicating with device

unable to open database file

Traceback (most recent call last):
File "site-packages/calibre/gui2/device.py", line 87, in run
File "site-packages/calibre/gui2/device.py", line 502, in _books
File "site-packages/calibre/devices/kobo/driver.py", line 1671, in books
OperationalError: unable to open database file

When sending a book to the device, there are no error messages, and the book does show up on the device, but it is not visible by Calibre (not in the database when I look at 'On Device').

Any ideas? Thanks!

An update, David --

Today my Kobo upgraded to the latest firmware (3.11) and now everything is once again fine with Calibre and all plugins. Thank you for your time.

Good to hear. But, I can't think of a reason it wasn't OK before..

Looks to me like DB corruption was likely. The upgrade probably does a repair?

Hi thanks for creating this plugin! i got my h20 and am creating many collections with it. But i have noticed that when i plug it into the computer, before the backlight would turn off and theres that still image. But now the backlight stays on while connected to pc. Is there a way to remedy this?

The light staying on is a change in the firmware. It used to always turn off but Kobo changed something recently with how the devices connect. Because of this, the light doesn't always turn of. Or at least, with my Glo it sometimes turns off and sometimes stays on. But, the eject behaviour is so much better that I don't care.

You may be better off asking in the Kobo device forum here, someone there may know or may figure something out in the future and not everyone reading that forum reads this one (or even this thread).

Well its just the first 10 times i plugged it into my compy, the light always switched off. Then i installed the kobotouchextended plugin and it started getting wonky and staying on so i assumed it had something to do with that. But if everyone is getting this effect then ill just leave it.

Ok, I can see that. But, calibre and the drivers are only responding to what the OS presents it. Whatever decides to turn the light off, or not happens a lot earlier. If you want to check, connect without calibre running and see what happens.

Sorry I am not really up to date on how this plugin works, but I wonder if it is possible for the wrapper divs that are present in kepubs synced from Kobo to be added to the kepubs that this plugin creates?

The Kobo kepubs look something like:
Code:
<body>
  <div id="book-columns">
    <div id="book-inner">

      ...

    </div>
  </div>
<body>
It is possible to patch the device's built-in stylesheet to add some left/right padding to one of these divs, which cleanly works around a bug in the kepub reader that causes characters with large side bearing (such as f) to cut off when at the end of a line in full-screen mode.

However, without these divs, there doesn't seem to be any way to add padding to elements below body without potentially changing the layout of the book. (because some elements might already have padding.)

(Note that it is not possible for the patched stylesheet to add padding to the body element itself, as this tickles another bug in the kepub reader (or maybe just violates the kepub spec) which shifts the text right and results in even worse cut off problems.)
