Error communicating with device

[thegameksk]

I keep getting the following:
Device closed the network connection

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 90, in run

ControlError: Device closed the network connection

How do I fix this?

Hello,

Can you send us a debug log?

Also is this happening on wireless connection?

Thanks,

Here you go.

Edit: Now I sometimes get the error message host machine closed connection. It seems to happen with my picture heavy books which are large in szie and transfer slower.

This sometimes (on normal android devices, a lot of likebook mars with eInk) happens for me too.

Any updates? calibre suddenly couldn't connect to my Kobo device after I installed the latest version of firmware(Kobo Firmware 4.23.15505) days ago.

Here is the error message when trying to connect:

```

```

And it failed to backup my database too since it failed to connect:

```

BUT it actually successfully sent books to my Kobo Forma.

.

Looks like calibre's database is corrupted.
Try with new Calibre library.

Maybe the new firmware made some changes to database and calibre cannot hande it since the kobo device itself works totally OK.

I guess the calibre program needs updates.

I'm getting a similar error message (see below). I was able to connect wirelessly with my Samsung Tablet just fine, but received the error message when trying to connect wirelessly to my Samsung S9 phone. Any brains out there bigger than mine that can offer assistance? TIA.

Device closed the network connection

You need to get CC's logfile (Settings->Other->e-mail a debug log->insert your own address). Check it for something obvious (one example:I have a lot of issues where CC refuses to sync specific files on specific devices because of filename length issue and it will be different if CC's folder in different places).

Or just don't change e-mail in this dialog but add some words about what you did and send it to CC's developers.

If you decide to post this log here - better check it doesn't containt something you don't want other to see (like books you hve)

Thanks vikarti; prior to reading your response I tried the old standby of rolling back Calibre to v4.23. That solved the problem I posted about above. Now I've got a problem with the count pages plugin, but that's another thread.

Thanks again.
