Eu consegui um novo "servidor doméstico" que possui portas USB 3. Infelizmente, até o momento, não consigo usar meu disco rígido externo em um gabinete USB 3.
Quando digito lsusb , o dispositivo aparece pela primeira vez na lista. Teoricamente, eu deveria ver isso agora como /dev/sdb , mas isso não acontece.
Eu observei o que acontece quando eu conecto o dispositivo usando dmesg :

O mais estranho é que parece que o dispositivo é detectado no início corretamente, depois é desconectado várias vezes e, finalmente, as coisas vão realmente para o sul e o dispositivo desaparece. lsusb agora não mostra mais o gabinete.
Outro dispositivo USB 3, um disco rígido menor, produz vários erros ao conectar, mas finalmente o dispositivo aparece como /dev/sdb
Estou usando o kernel 4.9.0-040900-genérico (mesmos problemas com o kernel 4.8. *) em uma máquina de 64 bits, o ubuntu 16.10.
