Unidade USB reconhecida nos logs, mas nenhum arquivo de dispositivo para ela

Question

Estou tentando montar uma unidade flash ( 16 GB Cruzer ) na área de trabalho do Arch Linux. Funciona bem no meu laptop Arch Linux, por isso não é um problema com a unidade.

A unidade está em /var/log/messages.log.3 :

Dec 16 20:20:45 localhost kernel: [5876090.739078] usb 2-2: new high speed USB device number 2 using ehci_hcd

Está em lsusb :

Bus 002 Device 002: ID 0781:5530 SanDisk Corp. Cruzer

Mas ele não está aparecendo quando eu executo fdisk -l como root (ignoro os erros; eles são de todas as Tabelas de Partição GUID que tenho em minhas outras unidades):

Ele não aparece como um arquivo de dispositivo em /dev :

Estes são todos os meus discos rígidos comuns, como você pode ver na saída do fdisk acima.

    

Answer 1

Esta mensagem é para um dispositivo USB reconhecido. Normalmente você também deve ver mensagens sobre armazenamento em massa, notáveis sobre a capacidade da unidade.

Teste modprobe usb-storage para carregar o driver para discos flash.
