You might try a nifty gui based package called hardinfo. I believe it is in the Debian repositories.
"HardInfo is a small application that displays information about your
hardware and operating system. Currently it knows about PCI, ISA PnP, USB,
IDE, SCSI, Serial and parallel port devices."

P.S, It should be available in RPM form as well. I have installed it on a Fedora PC.
