I can't see sound device using "esd -h" command

[Rocky Zhang <rocky userful com>]

Hi,

I installed Fedora 2 on my machine (Athleon CPU). And I connect 1 USB
Labtec Headset to my keyboard USB hub. The system seems recognize fine
when I run "kudzu" again. But if I use "esd -h" command, I can only see
"hw:0" whch is internal sound card. The Labtec sound card is missing. I
wonder if I missing something to install in Fedora 2. Can anyone else
tell me about it?

Part of /proc/bus/usb/devices is:

And the messages of system (/var/log/messages) is:
