CD/ DVD/ 蓝光设备无法检测

我无法让新安装的 Ubuntu 11.10 识别我有 CD、DVD 和蓝光驱动器......

这是我在其他论坛帖子中读到的有关该主题的一些常见终端命令的输出：

$ ls -l /dev/{cd,dvd}\*
ls: cannot access /dev/cd*: No such file or directory
ls: cannot access /dev/dvd*: No such file or directory

$ sudo lshw -c disk
  *-disk:0

       product: ST9250421ASG
       vendor: Seagate
       physical id: 0
       bus info: scsi@2:0.0.0
       logical name: /dev/sda
       version: DE12
       serial: 5TH00M12
       size: 232GiB (250GB)

       configuration: ansiversion=5 signature=00099b7e
  *-disk:1

       bus info: scsi@3:0.0.0
       logical name: /dev/sdb

       serial: 5TH00HHY
       size: 232GiB (250GB)
       configuration: ansiversion=5

$ sudo lshw -c drive

此外，这是我的 fstab 文件：

\# /etc/fstab: static file system information.
\#
\# Use 'blkid' to print the universally unique identifier for a
\# device; this may be used with UUID= as a more robust way to name devices
\# that works even if disks are added and removed. See fstab(5).

\# / was on /dev/sda1 during installation

抱歉，我对 Linux 自动检测/安装过程确实不太了解。如能得到任何帮助我将不胜感激！

啊，显然 Ubuntu 默认不会检测我的连接类型……在安装了操作系统的所有更新后，它会自动检测并进行相应安装。

我的错。
