Hello again and good evening...

After a few days working as a charm my device connection with Calibre is again giving me problems.

I am onto Calibre 7.2 last version and with last Kobo firmware, in Calibre I use all the kobo related plugins.

Now when I connect the reader to the computer (windows 11), Calibre launch the message of "communication error with the device" and the following log:

calibre, version 7.2.0
ERROR: Error: Error en la comunicación con el dispositivo

CorruptError: database disk image is malformed

Traceback (most recent call last):
File "calibre\gui2\device.py", line 104, in run
File "calibre\gui2\device.py", line 558, in _books
File "calibre\devices\kobo\driver.py", line 2028, in books
File "C:\t\t\apsw-42s16m2x\src\cursor.c", line 240, in resetcursor
apsw.CorruptError: CorruptError: database disk image is malformed

Still I can send files from Calibre to my Kobo but they don't last marked as transfered.

Another question is if there is any difference between epub and kobo epub formats, as since i installed the plugins the ebooks they have been transfered in that format (kobo epub). I normally only modify the ebooks i download (cover, publisher...) I do not convert the epubs through calibre as i don't see any adventages doing it.

Thanks in advance for your help!
