Calibre/Computer/Kindle not communicating

[CatMintCat]

Calibre: Version 5.43 downloaded yesterday
Kindle: 7th generation
Computer: Windows 10

I have been using Calibre with this kindle and computer for several years. When I plugged the Kindle in yesterday, the "send to device" button didn't appear. I upgraded the Calibre software (from 5.41). I've tried all the USB ports with no success. The computer is kept updated constantly and isn't giving any problems. Calibre looks as it always does, except for that one button.

The kindle, while older (2014, I think) is still working perfectly in everyday use, and I last used this combination of devices about a month ago with no issues.

Does anyone have any idea if this is fixable?

Is this an e-ink Kindle or a Kindle Fire (ie tablet) device?

Does Windows itself see the device (until it's detected by Windows, calibre cannot see it)?

It's an e-ink Kindle.

The computer doesn't see it as a drive, but I'm sure it never has.

Does WINDOWS (explorer) see the Kindle???
Calibre uses Windows USB services.

If Windows DOES see it: Check Preferences: Ignored Devices
(does not show if there are none)

The computer doesn't see it. It never has.

If Windows doesn't see it, calibre can't see it.

Why not try the instructions in https://www.mobileread.com/forums/sh...d.php?t=118560 and paste the log

So how do I get Windows to see it? It's not showing up in File Explorer and, as far as I know, it never has.

I've already tried those as follows:

Make sure that you are connecting only a single device to your computer at a time. Do not have another calibre supported device like an iPhone/iPad etc. at the same time.

Check - nothing else connected.

Make sure you are running the latest version of calibre. The latest version can always be downloaded from the calibre website

First thing I did when I started having problems.

Ensure your operating system is seeing the device. That is, the device should be mounted as a disk that you can access using Windows explorer or whatever the file management program on your computer is.

That's not happening.

If you are on Linux and the device is an MTP device, make sure it is not automounted by the OS/file manager as only one program can access an MTP device at a time.
On Linux, device might fail to mount if after updating kernel system wasn't rebooted.

Not using Linux

In calibre, go to Preferences->Ignored Devices and check that your device is not being ignored
In calibre, go to Preferences->Plugins->Device Interface plugin and make sure the plugin for your device is enabled, the plugin icon next to it should be green when it is enabled.
If all the above steps fail, go to Preferences->Miscellaneous and click debug device detection with your device attached and post the output in this forum:

None of these operations are available.

All I have in preferences is:

Change Calibre behaviour
Run welcome wizard
Get plugins to enhance Calibre
Restart in debug mode
Restart ignoring third party plugins

You may have a bad USB port on the device.
You never said WHICH MODEL, only Gen 7

Android you use the cable (if you want to transfer files). based (Fire) need you to enable the USB port on the device EACH TIME.

I really think you have a Kindle issue here. I can move this thread to the Kindle section of MR. Just ask

[CatMintCat]

Yes, please, if you think it will be helped better there.

I have tried it in all my USB ports, both directly into the computer and using the hub I have. They are working for other things, but the Kindle doesn't show up.

I thought Gen 7 was the model. How do I find out more detail?

It could well be a Kindle issue - it's old, after all. If it needs replacing I can do that, it doesn't owe me anything, but it is working fine for other things.

I have been using Kindles since they were new, and this is the first time I've had any sort of issue (except for dropping my first one and breaking it). I don't know what I don't know.

From this site: https://www.howtogeek.com/733834/how...odel-you-have/

it appears that it is a Kindle Basic (7th Generation). So nothing fancy.

Select Preferences | Change calibre behavior then under Advanced, click Miscellaneous and then Debug device detection
