usbdnet mod to start in Suse 8.1

I want to bring up usbdnet for a device. I am doing it now by typing insmod usbdnet, it brings up Using /lib/modules/2.4.19-4GB/kernel/drivers/usb/usbdnet.o Warning: /lib/modules/2.4.19-4GB/kernel/drivers/usb/usbdnet.o symbol for parameter echo_tx not found To load this automatically, I tried a couple of places in Yast2's editor /etc/system config module area for usb to add usbdnet. Not sure if I'm trying it in the right section or if in fact this the right procedure? Also the warning for symbol for parameter echo_tx not found, I'm clueless on what it's looking for. Thanks John
