Problema (¿raro?) con Ubuntu y reproductor MP3 USB

Archivado
Qué tal, quería comentaros un problema raro que tengo con un MP3 que compré hace poco: parece que no necesita drivers, ya que se detecta como almacenamiento en masa y al enchufarlo aparece en los dispositivos montados y se abre en nautilus. A veces.

Otras veces al conectarlo no reacciona, el aparato se queda como colgado y no aparece en la lista de dispositivos, ni por supuesto nautilus lo abre. Talmente como si no hubiera conectado nada.

A veces se monta bien pero al copiar archivos el proceso de copia se congela, se queda atascado en un archivo y el tiempo estimado empieza a subir, y vuelta a lo comentado el párrafo anterior: hasta que no reinicio el ordenador ya no lo reconoc, y a veces ni aun así. Parece que lo hace de forma totalmente aleatoria y no sé qué puede causarlo, pero descarto algún defecto del reproductor o el cable porque los devolví y el que tengo ahora es otro del mismo modelo, y que da el mismo error.

Llamé incluso al servicio técnico de la casa, pero la chica parecía que no tenía mucha idea y cuando le pregunté si podía ser porque usaba linux me dijo que sí, que lo sentía y que (literal) "el monopolio de Microsoft se extiende hasta los MP3".

No creo sin embargo que el problema sea entre Linux y el aparato, ya que entonces no funcionaría nunca ¿no creéis? ¿Qué puede estar pasando, cómo creéis que lo puedo arreglar?

Venga, gracias.
Bou, cuando te pase esto, cuelga aqui la salida que té de el comando 'dmesg', asi podremos saber que esta pasando. Por ejemplo, cuando conecto mi pendrive, una de las cosas que salen en el dmesg, son cosas de el estilo:
SCSI subsystem initialized

A ver si posteando lo que te sale a ti despues del error vemos que te pasa exactamente.

Desconocía este comando, parece que al introducirlo me dice todo lo que ha ocurrido en el sistema desde que lo he encendido ¿no?

En todo caso, esto es lo que creo que nos importa:

[4298618.275000] usb 4-5: new high speed USB device using ehci_hcd and address 3

A mí me suena medio chino, a ver si alguien saca alguna conclusión.

Gracias.



P.D. Hace un momento ha detectado el USB, sin hacer nada yo, llevaba puesto desde que he puesto el mensaje hace media hora.

He vuelto a ejecutar el comando que me has dicho y:

Mas o menos. 'dmesg' imprime los mensajes que ha dejado el kernel en el ring buffer.




Cuanto al problema... por un lado lo unico raro que veo es:
[4298618.369000] usb 4-5: device descriptor read/all, error -71

No conozco el significado de ese codigo de error, aunque de momento sabemos que el sistema detecta tu MP3.
Viendo el resto de mensajes parece que a veces no es capaz de leer la tabla de particiones del mp3. Yo provaria de cargarme esa tabla y volverla a crear, en el momento que te la reconzca. Es decir, lo que haria yo es:
- Ir enchufando el pendrive hasta que lo reconozca
- Hacerme un backup de mi musica favorita
- Desmontar el pendrive
- Reparticionar el pendrive (con cfdisk por ejemplo), es decir, me cargo la partcion fat32, y la vuelvo a crear.
- Formatear la partcion fat32. Diria que es con 'mkfs.vfat /dev/sda1' (asegurate que sda1 es el mp3)

A ver si esto te funciona.

Nah, eso ya lo probé el primer día y nada... todo esto es con el aparato ya formateado. A fat16, porque haciéndolo a fat32 luego no funciona.

He vuelto a ejecutar el comando que me dijiste cuando se ha quedado colgado copiando archivos, y me da esto:

[4302311.713000] FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

[4302645.260000] lost page write due to I/O error on sda1


La última parte, a partir de SCSI error, se repite muchísimas veces. :(
lo formateaste desde linux o desd eel rpopio aparato?
No creo que te sirva de ayuda, pero con mi repro MP3 (Innovix 1Gb) me pasa lo mismo tanto en Windows como en Linux. Tengo que ir a ver si me lo descambian, pero si dices que a ti no te ha mejorado la situación, mal asunto.:-(

Saludos

Desde el propio aparato.

Methenx, lo he probado muy muy poquitas veces en Windows pero las veces que lo he hecho ha ido perfectamente.
