ERROR: error communicating with the device

finalgirlfall · 05-03-2023, 04:00 PM

hi, so:

i have a kindle fire hd 10, 7th generation. i'm trying to import books (pdf and mobi) to it using calibre's send to device function and a usb cable. i keep getting an "error communicating with the device." i ran cmd.exe > calibre-debug -g and it spat this out:

Code:

calibre 6.17  embedded-python: True
Windows-10-10.0.22621-SP0 Windows ('64bit', 'WindowsPE')
('Windows', '10', '10.0.22621')
Python 3.10.1
Windows: ('10', '10.0.22621', 'SP0', 'Multiprocessor Free')
Interface language: None
Successfully initialized third party plugins: DeDRM (7, 2, 1)
QPA platform: windows

ApplicationPaletteChange event ignored
Using calibre Qt style: True
ApplicationPaletteChange event received

i've also tried restarting my laptop, and booting it into safe mode, neither of which has helped. advice appreciated!!!

edit: oh! and the "error communicating with device" details say this:

Code:

calibre, version 6.17.0
ERROR: Error: Error communicating with device

One quick question. When you connect your Fire HD to your computer without calibre running, do you see the storage on the device mounted in File Explorer. If that does not happen, calibre will not see the storage either.

Other item is that you are using an old version of DeDRM tools. See NoDRM's github repository for the latest version.

That is an error communicating with the device. Usually, this kind of error can be fixed by
following the steps below in sequence. First:

1) Try rebooting both the device and your computer
2) If that does not work, find the files driveinfo.calibre and metadata.calibre on the device
and delete them (you can use Windows Explorer or a file manager on the device itself to do this)
3) Reset the device

If none of those work, you can use one of the wireless communication methods described here:

when i connect my Fire HD to my computer without calibre running, i do see the storage on the device mounted in file explorer--i make sure to connect it as a media device (< kindle particularity...).

eta: also, i'll update deDRM tomorrow. thank you! <3

i was unable to update deDRM. when i tried to load the plugin from the zip file, there was apparently no __init__.py file. (see also--perhaps related--this pull request from github
here.)

i'm running windows 11, by the way--i neglected to mention that in my initial post.

The .zip file downloaded from github has two .zip files inside it. Those are what you need to install in calibre.

ok, so i'm sure i'll feel very silly once you really explain how to do it--but i really can't figure out how to install the DeDRM plugin from github! and ultimately i don't think DeDRM is the biggest problem--it looks from the output generated by calibre when it can't communicate with my kindle like it's an issue with some driver, and i'm not sure what to do about that! output reproduced below:

Code:

also, the DeDRM issue isn't currently terribly relevant--i uninstalled the old, outdated plugin when you informed me that it was outdated, and so for now the primary issue is the error communicating with the device.

What happens if you try "Preferences->Miscellaneous->Debug device detection"?

it says,

calibre, version 6.17.0
ERROR: Device already detected: A device (Fire) is already detected by calibre. If you wish to debug the detection of another device, first disconnect this device.

Those have nothing to do with DRM. (that just stops you from opening the book)

That is a file system error. Did you follow the instructions from Kovid?
A rogue A/V can block things. Defender just works with Calibre.

re: DRM--i know, i know!!

yes, i followed Kovid's instructions. i got the same error each time:

Code:

what's "a rogue A/V"? (i am not very knowledgeable about tech terms...)

Please do not call it a Kindle Fire. Amazon stopped using the name Kindle with their tablets because there was too much confusion with Kindle Readers both using the name Kindle.

Amazon calls them Fire HD 10 tablet.

A Rogue A/V is an anti-virus program that thinks what you are doing is dangerous and blocks it.

Another thing to try is to reboot into safe mode and try there are nothing you run on startup will be running (aka not in the way).

Yet again you demonstrate your failure to read what people post, the OP states quite clearly in the opening post that they tried safe mode.
