 Posted: Sun Jan 23, 2005 6:09 pm Post subject: Ajuda numa pen-drive usb (RESOLVIDO) |
 |
|
Olá ppl,
Comprei uma pen-drive usb e estou dificuldades para a instalar e configurar.
Alguém me pode dar umas dicas?
Aqui vão uns dados do meu sistema:
dmesg | grep usb:
| Code: | usbcore: registered new driver usbfs
usbcore: registered new driver hub
usbcore: registered new driver usb-storage
usbcore: registered new driver usbhid
drivers/usb/input/hid-core.c: v2.0:USB HID core driver |
fstab:
| Code: | | /dev/usb /mnt/pen usbfs noauto,users 0 0 |
lspci | grep USB
| Code: | 0000:00:1d.0 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #1 (rev 02)
0000:00:1d.1 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #2 (rev 02)
0000:00:1d.2 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #3 (rev 02)
0000:00:1d.3 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI Controller #4 (rev 02)
0000:00:1d.7 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller (rev 02)

Quando faço o mount do /dev/usb aparecem 5 pastas: 001 002 .... e uma file devices:
| Code: | T: Bus=05 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2

O seu fstab deveria ser:
| Code: | | /dev/usb /mnt/pen vfat noauto,users 0 0 |
no lugar de:
| Code: | | /dev/usb /mnt/pen usbfs noauto,users 0 0 |
Como root, veja quais dispositivos USB estão conectados digitando:
Se não tem o lsusb instale-o:
Verifique também se seu kernel tem suporte a SCSI generic, e USB Mass Storage:
Device Drivers --> SCSI device support --> SCSI generic support
Device Drivers --> USB support --> USB Mass Storage |

Já tenho o usbutils instalado.
No lsusb tenho:
| Code: | Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000 |
O que é que deve faltar?

Se você colocou o seu pen-drive numa porta USB, ele deverá mostrar em qual está e outras informações sobre o dispositivo. Por exemplo, o meu fica assim:
| Code: |
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0ea0:6828 Ours Technology, Inc.
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
|
Isto é só pra você se certificar que o seu pen-drive está realmente conectado. O que importa mesmo é o seu fstab e as outras questões sobre o kernel. |

ok essa parte já está, THX dafaca, tenho no lsubs
| Code: | Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 002: ID 0ea0:2168 Ours Technology, Inc.
Bus 001 Device 001: ID 0000:0000 |
O problema está relacionado agora com as permissions:
Quando faço cp ficheiro.txt /mnt/pen tenho
| Code: | | cp: cannot create regular file '/mnt/pen/ficheiro.txt' : Permission denied |
Já tentei chmod 777 /mnt/pen mas nada

Tente colocar umask=022 nas opções da entrada no fstab.

Não consegui 
Com o fstab (abaixo) obtenho a seguinte mensagem:

Não seria um /dev/sdX no lugar de /dev/usb ??
Já que o seu hd é o /dev/sda talvez o seu pen-drive seja um /dev/sdb. Veja no seu /dev quais dispositivos SCSI (sdX) estão disponíveis e teste-os. |

Só tenho sd , sda, sda1,sda2,sda3 não existen nenhum sdb 
No sd tenho 4 dispositivo com nomes estranhos c0b0t0u0, c0b0t0u0p1....c0b0t0u0p3 ???
Mas parece-me estranho que detecte o pen mas não consiga fazer um mount ??

Ok, faça o seguinte:
* Conecta o seu pen-drive numa porta usb.
* Como root faça um dmesg:
| Code: | | #dmesg | tail -n 25 |
Atente para as menssagens referente ao seu pen-drive, nelas encontrará qual dispositivo reservado para o seu pen drive. |

Como root você consegue ler? Se sim, tente umask=0 (não 022).

Observe que o kernel reservou o dispositivo sdb pro pen-drive.
Se você tem um kernel compilado para suporte a Generic SCSI e USB Mass Storage, não tem porque dar erro. Já tentou isto:
| Code: | | #mount -t vfat /dev/sdb1 /mnt/pen |

Agora é a minha vez, como já existia este topic aproveito para postar aqui o meu problema. Comprei ontem uma pen usb com leitor de mp3 incorporado (mto baradinha  ) que no manual afirmam ser compativel com linux a partir de 2.4.2.
Quando a ligo tenho um problema estranho no meu dmesg

Fica constantemente a reiniciar a ligação à pen ou então a propria pen (no lcd tambem aparece uma mensagem de "startin")... Já alguem teve um problema parecido? Assim nem seqer posso pensar em formatar a pen, como já vi por aí alguem dizer que era preciso fazer em alguns casos. |

| Problema resolvido, aparentemente há um bug que impede certas versões do kernel de funcionar com alguns dispositivos USB, um upgrade do kernel para 2.6.11 resolveu o problema |

Primeiro vc tem que ver em qual sd ele irá ser instalado, como por exemplo sdb1.
Para vc ver em que ele irá se instalar, vc vai no terminal com o superusuário, deixa o pen desconectado e da o commando:
tail -f /var/log/messages
Então estara mostrando os log da máquina, então espera uns dez segundos e conecta o Pen, vc vai ver que ele começara a montar seu Pen, então quase nas últimas linhas irá mostrar em qual sd ele estará.
Quando vc souber em qual sd ele se conectou, vc apertara Crtl+c, e irá digitar o commando:
mount /dev/sd(o qual seu pen conectou) /mnt/
Exexplo:
mount /dev/sda1 /mnt/
Seu pen estara conectado
Va em uma pasta qualquer no ambiente grafico, e va na barra em Arquivo, depois Abrir Localização...
e digite
/mnt/
Vc irá ver seu pen drive abrir
Flw, boa sorte. |
