[Device Plugin] Kobo Touch Extended Driver - Page 156

After installing 5.1 I noticed that this plugin was removed.

When trying to install it I get this error.

Quote:

I don't believe I had this problem with 5.0.1

Same here, Calibre is not recognizing my Libre H2O after 5.1 update. Kobo Extended Driver is missing and I'm not able to (re)install it

Same happened to me.

If you are unable to install the Extended Driver, click on Preferences -> Ignored Devices (under Sharing).

There you will find the original Kobo plugin that was disabled when you installed the Extended Driver. Remove the check mark.

Thanks! It worked

With Calibre 5.1,the KoboTouchExtended driver has vanished. And that's without installing the latest beta.

It's happening here as well. But, if I run in debug mode or from source, it is loaded with no problems. That's going to make it hard to debug

Thanks for the 'Heads Up'. I will hold off updating until this gets sorted

I was noticing that the KoboTouchExtended, Kepub Input, Kepub Output, Kepub Metadata Reader and Kepub Metadata Writer plugins were all removed. An attempt to reinstall gave an ImportError message similar to the one from the KoboTouchExtended driver. This seems to be an issue with the import line in _init_.py.

Code:

from calibre_plugins.kobotouch_extended.device.driver import KOBOTOUCHEXTENDED

from calibre_plugins.kepubin.conversion.kepub_input import KEPUBInput

from calibre_plugins.kepubout.conversion.kepub_output import KEPubOutput

from calibre_plugins.kepubmdwriter.metadata.writer import name KEPUBMetadataWriter

from calibre_plugins.kepubmdwriter.metadata.writer import KEPUBMetadataWriter

Edit: To be a total pain, they will install in debug mode and survive a calibre shutdown and restart into debug mode. A normal calibre startup happily removes them.

Edit2: Running from source does not let me install. See attached image.

The structure of these plugins are all the same, so, I assumed they would all fail, but, I hadn't checked them. I assume it is related to import not being threadsafe but, I can't see a change that would have triggered this.

Somehow the disappearance of the extended drivers prevented Calibre from detecting my device at all. It showed up in Windows Explorer but Calibre wouldn't detect it. When I rolled back to 5.0.1 and put the drivers back it detected just fine. That's odd.

The deletion of the KoboTouchExtended driver does not automatically re-enable the standard KoboTouch driver so basically, you had no Kobo driver.

I have done some playing, and the problem appears to be with importing from "calibre.ebooks.oeb.polish.container". If this is done when the plugin is loaded, it will fail. If it is done later, it works. I have no idea why. I assume it is related to the thread-safe issues with importing in Windows, but, I am not sure. Or, it might just be that what we were doing was wrong.

The attached beta is a quick-and-dirty hack to move the import to when it is actually needed. I have not done much testing, but it seems to work for the few books I have tried.

If this works for others, I'll look at the other kepub plugins as well.

Sorry but for me, the install errors out either running the binaries or running from source. BTW, was the run.cmd supposed to be in the .zip file?

That sounds like a circular import, just moving the offending import into the method wher eit is used will fix that.

Weird. It works here. And I have to admit, my first thought is that you have tried installing the wrong version. Anyway, I have made a couple of other changes with what Kovid said in mind. Can you try the attached version?

Also, the released version is working here with the 5.1.1 beta. Or at least the portable version of the beta.
