libmtp cannot open your device, which means either that it has been mounted by some other program, like your desktop file manager or that you are running some kind of sandboxed calibre like the flatpak version. Use the official binaries from https://calibre-ebook.com/download_linux

Yes, I didn't realize what that I have to Unmount the Kindle from Linux.
After doing the Unmount and laving the cable still connected, I restarted Calibre and it detected all good.

Thanks!

I go to System Monitor -> Processes and stop, not kill, gvfs-mtp-volume-monitor to prevent desktop and Caja mounting any MTP device. I found that some devices give communications errors trying to use MTP after unmount. An old Sony phone is OK just unmounting, but the Mars doesn't work.

So unless I want to use the file browser I now "pause" gvfs-mtp-volume-monitor by right click before connecting the USB cable. It will re-start if you kill it.

This is with the Mate Desktop. I found that other desktops on Mint do allow disabling mtp automount, but Mate / caja ignore the settings.

The problem is really Google/Android insistence on using MS MTP scheme instead of USB Mass Storage. I suspect to do with DRM, or just stupidity as all Linux gadgets without Android seem to use Mass Storage, not MTP.
MTP even on Windows may only allow one host program at a time.
