我有一个外置 USB CD 驱动器：
# lsusb
Bus 001 Device 006: ID 13fd:1140 Initio Corporation <--
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514

Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
但它没有作为 /dev/cdrom 或其他东西安装，而只是作为 /dev/sg0 和 /dev/sda 安装。

我该怎么做才能让它被识别为 cddrive？
