I have a Kindle with many ebooks on it. I would like to back them up onto my desktop. I have a cable that will go from my Kindle to USB, but I don't know how to do this. Thank you in advance for all of your help.
The Kindle Fire does not automount in Ubuntu 12.04. The dmesg tail does not show any usb storage when Kindle is plugged in. Install package mtp-tools and mtpfs
Make a directory under /mnt named mtp
Plug in the kindle and mount it
Your kindle files should now appear under /mnt/mtp Browse for your books and just copy them off. I forget exactly where they were, maybe under /mnt/mtp/kindle Unmount the kindle (or command fusermount -u /mnt/mtp )
