olá pessoal,
estou tentando utilizar um mp3 genérico no ubuntu, mas estou com um problema bem estranho. Quando conecto o pen em qualquer uma das portas usb do computador, na tela do aparelho aparece um simbolo indicando que ele está estabelecendo contato com o computador, mas após alguns segundos este símbolo some e no lugar aparece o símbolo de recarga da bateria.
se eu digito "lsusb" quando o aparelho esta recarregando, absolutamente nada (referente ao mp3) aparece detectado.
resolvi então usar o comando lsb no curto intervalo de tempo em que aparece o simbolo de "ligando ao computador", e então ele é detectado, mas ao passsar uns dois segundos, digito lsusb de novo e ele já não está mais lá!
Só para constar, o pen esta funcionando normalmente no Windows. Também tenho outros mp3s que funcionan normalmente tanto no windows como no linux!
Não obtive sucesso alterando o fstab de diferentes formas, pois o mp3 "perde" a comunicação como pc...
Também não funcionou instalar o pmount e usbmount pelo synaptic...
quando digito dmesg no terminal, entre as diversas informações, estas me pareceram interessantes, apesar deu não saber interpretá-las:

aparentemente ele tenta conectar, mas alguma coisa o desconecta automaticamente!
aceito sugestões...
