In Calibre, the On Device column is empty
I have a Kobo Forma with ePubs loaded, yet in Calibre none are shown (as a tick) in the On Device column. Even a freshly side-loaded book is not shown.
Calibre sees the Forma via a USB connection to my PC using Windows 10.
I first noticed the issue when attempts to read ePubs in Forma failed because of a faulty authorisation in ADE. Even when this was resolved by reloading the ePubs, after being re-converted to ePub in Calibre, the files were not shown in the On Device column.
A related issue may be that when the Forma is connected to a USB socket with Calibre open, an "Error communication with device" warning pops up. The details of this are:
calibre, version 7.4.0
ERROR: Error: Error communicating with device
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
I hope someone will offer some advice
Thank you
