/ dev / dvd在我的centos 6上丢失了

我只是通过USB设备安装了一个最小的centos 6。 它工作正常。 但现在我无法安装DVD刻录机。 我什至不能find/ dev / dvd设备。 我想一个驱动程序是缺less的，但我如何find驱动程序？

系统的一些输出。

NEC设备是我的DVD刻录机。

所有与/ dev文件夹中的usb相关的东西。

• 装载和卸载需要几个小时才能完成？
• 在Linux上安装encryption驱动器/分区
• 外部驱动从/ dev / sda切换到/ dev / sdb
• 在Linux VMangular色中安装Azure blob容器
• 是否有一个标志可以传递给`df`或`mount`，使它们只显示本地挂载的文件系统的结果？

我应该看看其他地方，还是只在我面前的正确信息？
