Huawey Matepad Paper: error sending eBooks from Calibre

[gbaldi]

Good evening everyone, and thanks in advance for your help.
I have a Matepad Paper, which is recognised regularly by Calibre. However, when I try to send books to the device (any format) I get an error message:

calibre, version 6.26.0
ERROR: Error: Communication error with device

Failed to create folder named Books in ('Memoria interna',) with error: 2:PTP Layer error 2009: LIBMTP_Create_Folder: Could not send object info.
2:Error 2009: PTP Invalid Object Handle

Traceback (most recent call last):

I hope some of you can help me, I don't want to regret the purchase I just made.

Thanks!

Which OS?
Make sure no other program is accessing it and it's not "mounted".

Looks like it's USB MTP, not USB Mass Storage, so only one thing can access it.
Also make sure the device is in MTP mode not PTP mode.

Note that if using any OS using caja (e.g. Mint with Mate Desktop) or gvfs you will need to stop (not kill) gvf-mtp-volume-monitor or only the file manager can connect, not Calibre. On Mac OS and other Linux desktops you need to quit MTP helper or disable USB automount.

[QUOTE=Quoth;4355666]Which OS?

You are right, sorry: Mac OS 13.4 Ventura.

I'm very inexperienced and I'm not sure I understand what you kindly advised. I have tried ejecting the Matepad from the Mac (keeping it connected to Calibre) but I get the same error. With my Kobo and not even with an old Kindle have I ever had such problems and I am a little disoriented...
s there an easy way to configure Calibre (or the Matepad) in the correct way?

Thank you very much

I forgot to mention that I checked and the Matepad is set in MPT mode as you suggest.

Re: MacOS

if Android File Transfer has opened, you will need to close AFT before calibre will be able to see your Scribe.

The Kindle Scribe, Android phones and Android Tablets all have this issue.

The other Kindles (currently) and Kobos use the different USB Mass Storage mode, so don't have this issue.

Edit:
P.S. is it a Huawei Matepad Paper?

That is an error creating a top level folder on the device I think some MTP devices prevent you from doing so. So right click on the device in calibre and configure it changing the destination books are sent to, to an already existing folder.
