Request Help Kindle Fire HD6 4th Gen - Cant send to device

[m9ke]

I am unable to move a book from my Calibre library on my Linux desktop to a Kindle Fire HD6 4th Gen. I followed these steps:

• Powered up and unlocked Kindle
• Verified WiFi is turned on on Kindle
• Connected Fire to Desktop USB 3.0 port with known good cable
• Verified that Kindle was mounted on Linux desktop
• Started Calibre library on Linux box
• Started Calibre Content Server
• Right-clicked on book title in Calibre
• Saw Send to Device
• Saw that Send to Device > Send to Main Memory is greyed out
• Saw that Send to Device > Send to Storage Card A is greyed out
• Saw that Send to Device > Send to Storage Card B is greyed out
• This did not work. Tried it again with the Kindle connected but not mounted. That did not work either. Tried both EPUP and AZW3 file formats but no joy there either.

I am stuck. Suggestions welcome !
Thanks,
Mike

I suspect your Fire HD 6 4th generation is using a MTP connection. Linux and MacOS devices can only have a single program accessing a MTP device. If it is mounted on your desktop, you must dismount it from Linux and then let calibre mount it. How to dismount it is dependant on your unspecified Linux distro. You can also look into disabling automount for your Linux distro.

Just as a sidenote, your 2014 Fire HD 6, if my memory is correct, was the first generation where Amazon dropped Kindle from the name.

When Calibre first detects a device it asks if it should manage it. If you clicked no, then it would be added to the Ignored Devices list. Check if that's happened in Preferences -> Ignored Devices.

DNSB, thanks for your reply. I am running Ubuntu Mate LTS 24.04. You are correct the Fire HD 6 is an MTP device. In first troubleshooting this issue, I found that there are a number of MTP tools that were not installed. I added mtp-tools, go-mtfs, libmtp-common, libmtp9t64, libmtp-runtime, and jmtpfs. This did not help the issue. I am not knowledgeable about how MTP support works in Linux, so I may have missed something wrt MTP support in Linux.

Frogm4n, thanks for your reply. Good catch but a check in Calibre Prefs > Ignored devices showed that I have not specified any devices to ignore in this Pref.

The problem is that you do not want Linux to mount the device as then calibre is unable to access it. From what I (rather vaguely) remember for Ubuntu, you will need to stop the gvfs-mtp-volume-monitor process from System Monitor before connecting your Fire HD. Do not kill the process since it will automatically restart, just stop it.

Good luck!

Might work to disable automount in DConf Editor under the org.mate.desktop.media-handling key.

DNSB and Frogm4n: thanks for the follow up! I see gvfs-goa-volume-monitor in my System Monitor. I will try stopping (not killing) that process. Thanks too Frog4man. Think I will go with temporarily stopping gvfs-goa-volume-monitor because knowing me I might forget a persistent conf change!

Cheers,
Mike
