Fail message from Calibre about Kobo Touch

Removal of the config folder IS the recommended procedure for a difficult corrupted 'configuration'. It will be recreated (the Welcome Wizard will run) when you next start Calibre.

It's not hard to say. I believe the last time you could have connected to calibre an not have gotten that warning when connecting was version 0.8.59, because that warning was inserted in 0.8.60

As theducks stated calibre will still send books to your device fine. I think the auto-metadata management may not work because for the safety of your Kobo's database calibre will not write directly to it until the driver is updated.

If you wish to return to version 0.8.59 simply download it from Sourceforge. Find the calibre directory that has the calibre.exe file and delete that folder then execute the msi file downloaded from sourceforge. Since there is no major calibre database change it is just that simple. There will be no orphaned folders or files doing it this way.



As stated previously your Kobo will work fine with the latest version of calibre. It will work exactly as every eReader works with calibre except for what was stated in the warning. You may have to update collections and delete books via your device.

Personally if I had a Kobo I would be using the latest version of calibre because a fix for showing Kobo books on device was included. Additionally you wouldn't be chancing possible corruption of the database on your Kobo.

Good Luck.

The change being discussed here is a simply a warning. This was put in on the 7th of July and went into calibre version 0.8.60. It tests what database version is found on the Kobo device and compares it to the versions that the calibre driver understands. The driver is coded for up to database version 33. Unfortunately, no one has been keeping this up to date. But, luckily there had been no changes to the Kobo database that caused any problems.

I don't know exactly what firmware version DBVersion of 33 is from. From my Kobo Touch, I have copies of the database from various times. I have one from when I recently did a factory reset the device. It has DBVersion 29 for firmware 1.9.11. I also have DBVersion 36 which I came from either 1.9.14 or 1.9.16. The previous firmware I was using was 1.9.17 which DBVersion of 50.

I have had a good look at the different versions of the database and the driver code, and there are no changes in the structure anywhere the calibre uses. So, it is safe to continue using calibre with these firmwares. I don't have a Kobo Wireless, so I can't check it. But, from comments from other people here, it is still OK.

Now the firmware that triggered all this, V2.0.0 for the Kobo Touch, is also safe with the current driver. Again, the database structure has not changed in the areas that the driver touches. But, there have been some changes that the driver doesn't go near and would be great to support. It now needs someone with the time and inclination to update the driver for this. I've had a look at it and have some ideas. But, I would want to split the driver into two. That would be either a Touch and a non-touch, or a pre- and post- firmware 2.0.0 drivers. Both ways have advantages and disadvantages.

...thanks for all that, I already went ahead & did scrub my XP PC of calibre; I "uninstalled" it, manually deleted calibre library & calibre2 folders and any other update files. Ran a registry "cleaner" then de-fragged the registry.

Yes, I decided to go back to 0.8.59 and installed that ( I have my own copies from about 0.8.43 onwards).

It ran the welcome wizard during installation so seems like a clean install and the only book in the library was the manual.

I transferred an ebook from Kobo to calibre as a test and that seemed to go ok.
However, when I transferred another free ebook from calibre to Kobo I got a longish technical error message.

But when I checked the Kobo, the book seems to have transferred ok ?

If it is of any interest my Kobo software shows thus:

1.9.17 (r37603, 3/16/12)

Dont know what the ...r37603... means but presume ...3/16/12 is the date of release for that firmware update.

When calibre puts an ebook on the Kobo, it copies the book to the device, updates the metadata in the copy of the book on the Kobo, (optionally) creates covers on the Kobo, updates a file on the Kobo and reads/updates the database on the Kobo. But, as far as the Kobo is concerned, it is only getting the file onto the device that is important. When it is disconnected, it processes any new file and adds it to its database.

As to what went wrong, we need to see the full error to have an idea.

"r37603" is a build number. A couple of the firmware versions have been removed and release quickly with a different build number.

Thanks for that, I like to find out what these things mean.

I've updated Kobo Desktop, but not without a synchronous diaphragmatic flutter (hiccup to you).

I'll leave synching and updating my Touch until tomorrow...
