Same issue here. Different Kindle models. Can confirm that this is a calibre on Ubuntu issue. calibre:3.21.0+dfsg-1build1 Ubuntu:18.04.3 LTS
Verified by testing with: 1. 2 different Ubuntu machines, same USB cables, same set of Kindles - same problem manifests itself 2. A different Arch Linux machine, calibre 4.9.1-1, same USB cables, same set of Kindles - no problem at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1842492 Title: Device disconnects from Ubuntu when I send ebook via Calibre To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/calibre/+bug/1842492/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
