O Ubuntu 15.10 não reconhece minha unidade flash USB 3.0

Question

Eu tenho uma memória flash de 8 GB USB 3.0 Silicon Power. Eu estava usando no meu laptop, que tem apenas três portas USB 2.0, até que ele não foi mais montado no Ubuntu depois de ser conectado. O problema é que o stick não aparece em nenhuma saída do sistema. Eu tentei sudo fdisk -l , lsusb com meu pendrive sendo conectado. Não tenho idéia do problema com meu pendrive, pois ele funciona corretamente no Windows. Eu não sei o que tenho que fazer.

Aqui está a saída de dmesg|tail :

E aqui está a saída de lsblk :
