Kindle Paperwhite Ubuntu 14.04

Недавно я купил Kindle Paperwhite. При первоначальном подключении к ноутбуку Ubuntu 14.04 у меня не было проблем. Kindle был смонтирован, и я поместил на него несколько электронных книг, используя Caliber. Тем не менее, теперь я хочу добавить еще несколько книг, но Ubuntu вообще не поднимает устройство.

Я проверил порты USB и кабель, загрузившись в Windows, там обнаружение происходит немедленно.

Так что что-то не так в моей конфигурации монтирования Ubuntu (внезапно), но я понятия не имею, что. (или почему это вообще произошло).

Исходя из этого, я думаю, что с соединением что-то не так ...
