ALSA are sound drivers.

Probably not. Does sound work?

Here, lspci -v says

00:11.2 USB Controller: VIA Technologies, Inc. UHCI USB (rev 1b) (prog-if 00 [UHCI])
        Subsystem: Unknown device 0925:1234
        Flags: bus master, medium devsel, latency 32, IRQ 9
        I/O ports at 1800 [size=32]
        Capabilities: [80] Power Management version 2

00:11.3 USB Controller: VIA Technologies, Inc. UHCI USB (rev 1b) (prog-if 00 [UHCI])
        Subsystem: Unknown device 0925:1234
        Flags: bus master, medium devsel, latency 32, IRQ 9
        I/O ports at 1c00 [size=32]
        Capabilities: [80] Power Management version 2

00:11.4 USB Controller: VIA Technologies, Inc. UHCI USB (rev 1b) (prog-if 00 [UHCI])
        Subsystem: Unknown device 0925:1234
        Flags: bus master, medium devsel, latency 32, IRQ 9
        I/O ports at 2000 [size=32]
        Capabilities: [80] Power Management version 2

I think without the USB controller showing up in 'lspci' you'll have
no chance.

mf@gateway:~> /sbin/lsmod | grep usb
usb-uhci 20996 0 (unused)
usbcore 55136 1 [usb-uhci]

Does the Linux kernel 2.4.x support USB 2.0? Or is USB 2.0 hardware
compatible to USB 1.1?

Here is a step by step instruction from Suse.
