Calibre cannot communicate with Kindle Oasis.

bookw0rm2 · 07-19-2020, 12:47 PM

I've read through some of the other threads with the same issue, but nothing has helped me solve this problem... here is the error message I get -

calibre, version 4.21.0
ERROR: Error: Error communicating with device

Failed to access files in the main memory of your device. You should contact the device manufacturer for support. Common fixes are: try a different USB cable/USB port on your computer. If you device has a "Reset to factory defaults" type of setting somewhere, use it. Underlying error: [Errno 1] Operation not permitted: u'/Volumes/Kindle/driveinfo.calibre'

Any help would be greatly appreciated.

What O/S are you running and what version of it?

edited to ask:

Exactly "what steps" have you taken that haven't worked? That way we don't have to guess....

Kindle 5.12.5 and Calibre 4.21

I've reset the Kindle & used different USB cable (including a brand new Amazon OG one).

My laptop can see the Kindle & Calibre acknowledges that a Kindle is connected but then the error message appears...

Also wanted to mention that I went to check the files & folders setting on system preferences (I'm on a Mac) and Calibre doesn't show up there (no app does) so there's nothing to check... not sure if that's related but I found that solution in the FAQs..

Reset the SMC chip.

Let me quote it for you

On macOS if you get permission errors when connecting a device to calibre, you can fix that by looking under System Preferences > Security and Privacy > Privacy > Files and Folders.

No I mean, I know where to go but there's nothing showing up under Files & Folders... It's blank.

In your error message you have

Operation not permitted: u'/Volumes/Kindle/driveinfo.calibre'

the only cause for that I know of is the catalina security feature.

Thank you. I think the issue is because I'm running the Big Sur beta. I'll wait for the general release & check again

And that might be why in the second message in this thread, you were asked what O/S (operating system) and version you were running.

I think I'd still try the SMC reset. If the Kindle is not being detected by the o/s it points to either a h/w issue or an underlying o/s issue. If it were to be an o/s issue I'm sure you'd be seeing other Big Sur users with similar issues. At least if you can report it to Apple do!
