hello @all ^^


When my Fire HD 11 max is connected to my computer with the USB cable and I open Calibre, I get the following message:

calibre, version 8.7.0
FEHLER: Unbehandelter Ausnahmefehler: <b>WPDError</b>:C:\r\src\src\calibre\devices\mtp\windows\conten t_enumeration.cpp:439:Failed to EnumObjects() of folder from device:[hr=0x80042009 wCode=7689 name=INVALID_OBJECT_HANDLE] IDispatch error #7689: o21

When I click OK again, the message disappears and I can use Calibre. A connection to the Fire HD 11 Max seems to have been established. I can also say "Copy/Send to my device." But here's the problem. Even when I send the ePub/mobi files, they don't end up in the Books folder or appear in the Kindle library.

Is there any way I can get the books back into my Kindle library?
(So, after "Send to Device," they'll appear in my library on the device again.)

I'm not a fan of the online version with the server, as I'd like to have these books on my device, and downloading them from the server doesn't add them to my library either.

I've tried everything, but nothing helps.

Can anyone give me some advice?


thx in advance
