USB-накопитель не работает в Ubuntu 14.04 [закрыто]

Я недавно обновился до Ubuntu 14.04, и теперь моя флешка даже не мигает при подключении! Я тестировал флешку на ПК с Windows, и она работает нормально . Протестируйте порт USB на том же ПК на linux mint (двойная загрузка), он работает нормально.

lsblk команда показывает:

при отключении и повторном подключении USB-накопителя команда dmesg показывает:
