Ubuntu 10.10 não reconhece gravadora de DVD Samsung SH-S202J

[docetrago]

Preciso de saber como faço para que o Ubuntu reconheça a gravadora de DVD.

Estou usando Ubuntu 10.10 e a gravadora de DVD é Samsung modelo SH-S202J.

Agradeço desde já pela valiosa ajuda.

Algumas informações que tenho :

$ sudo wodim --devices
wodim: Overview of accessible drives (1 found) :
-------------------------------------------------------------------------
0  dev='/dev/scd0'   rwrw-- : 'TSSTcorp' 'CDDVDW SH-S202J'
-------------------------------------------------------------------------

$ sudo cat /dev/scd0
cat: /dev/scd0: Mídia não encontrada

$ sudo mount /dev/scd0
mount: no medium found on /dev/sr0

$ lshal | grep DVD
  scsi.model = 'CDDVDW SH-S202J'  (string)
udi = '/org/freedesktop/Hal/devices/storage_model_CDDVDW_SH_S202J'
  block.storage_device = '/org/freedesktop/Hal/devices/storage_model_CDDVDW_SH_S202J'  (string)
  info.product = 'CDDVDW SH-S202J'  (string)
  info.udi = '/org/freedesktop/Hal/devices/storage_model_CDDVDW_SH_S202J'  (string)
  storage.model = 'CDDVDW SH-S202J'  (string)

$ sudo lshal | grep CD
  scsi.model = 'CDDVDW SH-S202J'  (string)
udi = '/org/freedesktop/Hal/devices/storage_model_CDDVDW_SH_S202J'
  block.storage_device = '/org/freedesktop/Hal/devices/storage_model_CDDVDW_SH_S202J'  (string)
  info.product = 'CDDVDW SH-S202J'  (string)
  info.udi = '/org/freedesktop/Hal/devices/storage_model_CDDVDW_SH_S202J'  (string)
  storage.model = 'CDDVDW SH-S202J'  (string)


Curioso é que os dois comandos a seguir funcionam :

$ eject /dev/scd0 >>> A gaveta se abre
$ eject -t /dev/scd0 >>> A gaveta se fecha

$ ls -l /dev/cdr*
