O Ubuntu não vê meu Kindle (4ª geração) como dispositivo mtp

Question

Meu kindle da 4ª geração funcionou por apenas um ano, apenas conectando-o com um cabo USB-microUSB e transferindo os livros com calibre. Agora, desde um par de semanas que cobra, mas ele não fica montado, então eu não posso colocar novos livros dentro. Libmtp, mtptools, mtpfs e calibre são instalados e atualizados. Eu tentei usar cabos diferentes, com o mesmo resultado.
