Library and peripheral window behavior

[asw22]

I am presently expurging my Kobo SD from books present in the database, but not physically.
My Library and peripheral databases are quite large (ca 30,000 books). I need to check line after line books considered not present in the library against the library itself to be sure sometimes a book announced at not present is there on the SD...
The goal is to have a peripheral book list reflecting the peripheral written books.
My idea of fun, dont ask

My problem is when alternating between peripheral and library view, the view is not "stable": for instance, on the peripheral view, the list goes back after a while (ca 20 s) to zero. When you are at 15000, it's unpleasant.
On the library view, each time I open it the list has gone back by 500 books or so...
What happens, and what can be done?

It is as much fun as opening a book and systematically begins at first page, whatever the place where you closed your book last time...

Thanks!

Hello!

I have finally finished the cleanup of the database books not present physically. I have begun to fill it again and I am around 26000 without too much databse corruptions.

However, I have had to stop because of a bizarre event: the Libra 2 is not recognized by Calibre, and this happened overnight.
Here is the debug:

The bug is quite close to some reported here, but not exactly...

Windows recognized the Libra (this is as "Linux_file-stor_gadget")

My understanding is that the Libra should be recognized as an USB device - it is not - it appears only in the list of WPD ND:
'\\\\?\\swd#wpdbusenum#_??_usbstor#disk&ven_linux& prod_file-stor_gadget&rev_0401#8&36424527&0#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}#{6ac27878-a6fa-4155-ba85-f98f491d4f33}'

I have connected/disconnected the device all day, and Calibre recognized the device. I eject properly (or maybe I let it connected for charge) close the device and the day after no recognition...
There was no update on Kobo or Calibre, and it happened on 9.2.1 and 9.3.1.

Please note I am still able to connect via Calibre using the connect/share procedure...Except the database is not saved anymore; apparently this is possible only if the Libra is normally recognized as a peripheral, not a File.

I have also tested with an Aura H2O: no problem for the peripheral and the associated SD card. The same for various Pocketbooks...

It is baffling!

[theducks]

W10 assigns my L2 as F: And W10 does detect as a Linux File-Stor Gadget

Are you running other software on your L2? Than might change things.

Have you updated your Kobo Utilities PI in Calibre <<<There was backup save issues

[asw22]

The only software present on my L2 are Nickel and KOReader. The reder is sproperly recogbized and accessible by W (O: in my case).
I have upgraded Kobo Utilities but when I am connected in the File mode, all the actions pertaining to database (including saving) are greyed...

[asw22]

The funny thing is that I defined "User defined USB" Calibre driver with the L2 hex addresses obtained via Calibre, and desactivated the Kobo Calibre driver and this works...but I still cannot save the database, this feature is obviously linked to the recognition of the peripheral as a Kobo.
I have the feeling the Kobo driver for some reason has stopped recognizing my L2, even if still it recognizes the H2O...

Nope. Not Ignored.
