Eu tenho um laptop Thinkpad T520 com a dock station Lenovo 4338-35 que tem uma porta USB 3.0 (é azul, marcada com SS ). No entanto, meu Linux Mint 17.2 (baseado no Ubuntu 14.04) não o reconhece.

Se eu conectar algum dispositivo à porta USB 3.0, ele aparecerá em Port 5: Dev 5, If0, Class=Hub, Drive=hub/7p, 480M :

O dispositivo conectado a essa porta funciona normalmente, como em qualquer outra porta (USB 2.0).
Eu já vi outros resultados que as pessoas postaram que os dispositivos USB 3.0 devem aparecer com velocidade 5000M , mas eu tenho apenas 480M .

A versão do kernel é 3.16:

3.16.0-38-generic
Alguém poderia dar alguma pista de como reconhecê-lo como USB 3.0, por favor? Obrigado.
