Não consigo usar Pen drive de 1 GB

UBUNTU 7.10
Ao inserir o pen drive aparece a mensagem no dmesg:

Tentei em outro computador também com Ubuntu 7.10 e em outro com OpenSuse. Todos apresentam a mesma msg.
No Windows não tem problema.
Já tentei reformatar o Pen drive pelo Windows.

Olá larmando, seja bem vindo amigo.

Olha o que achei sobre isso.

Rodei o blkid e me retornou o seguinte:
/dev/sda1: UUID="e80f2e54-2528-49f2-860b-e24e6ce7b8aa" SEC_TYPE="ext2" TYPE="ext3"
/dev/sda2: TYPE="swap" UUID="73376a03-2b25-4b90-9ccc-f1c3a0d9f025"
/dev/sda3: UUID="b9e901f4-d656-41f4-9016-1fe14811ba0d" SEC_TYPE="ext2" TYPE="ext3"

ou seja, não está enchergando o pen drive montado.

Rode o lsusb e veja se ha algum dispositivo reconhecido nela

Antes de conectar o Pen Drive:
Bus 005 Device 002: ID 0db0:6877 Micro Star International
Bus 005 Device 001: ID 0000:0000 
Bus 002 Device 001: ID 0000:0000 
Bus 001 Device 001: ID 0000:0000 
Bus 004 Device 001: ID 0000:0000 
Bus 003 Device 001: ID 0000:0000

Após conectar o Pen Drive:
Bus 005 Device 003: ID 0dd8:e20b Netac Technology Co., Ltd
Bus 005 Device 002: ID 0db0:6877 Micro Star International
Bus 005 Device 001: ID 0000:0000 
Bus 002 Device 001: ID 0000:0000 
Bus 001 Device 001: ID 0000:0000 
Bus 004 Device 001: ID 0000:0000 
Bus 003 Device 001: ID 0000:0000

Como você pode ver, o Pen Drive é reconhecido pelo Ubuntu. Ele aparece no Nautilus como "Drive" e com o símbolo de USB. Ao dar duplo clique para montar aparece a msg: "Não foi possível montar mídia. Provavelmente não há mídia na unidade".

Fiz o upgrade para a 8.04 e rodando o dmesg continua aparecendo o seguinte:
