ServerManDann · 09-30-2021, 06:53 PM

Kobo Aura H20 version 1, firmware 4.28.18220. Calibre 5.28.0.
Was working fine last week, but today, after connecting device to USB, starts usual jobs, but two never complete. Backup device database still running after 15 minutes, reading positions waiting, for that to complete, I presume.
Could not stop jobs, could not eject device. Eventually had to unplug device and force shutdown Calibre. After unplugging device, got this error from Calibre:

Failed:Backing up Kobo device database
calibre, version 5.26.0 (win32, embedded-python: True)
Failed to backup device database: Failed: Backing up Kobo device database

[Errno 22] Invalid argument
Traceback (most recent call last):
File "calibre\gui2\device.py", line 89, in run
File "calibre_plugins.koboutilities.jobs", line 193, in do_device_database_backup
File "shutil.py", line 279, in copyfile
File "shutil.py", line 185, in _copyfileobj_readinto
OSError: [Errno 22] Invalid argument

I have:

replaced USB cable
used a different USB port
down-grade Caliber to 5.26.0
Windows updates, rebooted computer (Windows 10 Pro 21H1)

Suggestions, anyone?
