I would use either lshw, or hwinfo.

Hwinfo gives reasonably detailed information about your hardware and how
it is recognized by the kernel. It's in the universe repository. Here's
an example:

$ hwinfo --cdrom
14: SCSI 100.0: 10602 CD-ROM (DVD)

lshw provides a subset of what hwinfo presents:

$ sudo lshw --class disk
