Problems with eth0 (USB)
 

Hello !!
First of all, sorry for my poor English. I'm a beginner at Linux, and I have a problem. I'm developing a Networking Ethernet Device through USB using the CDC Ethernet NEtworking Control Model.
The Device Manufacturer is Infineon (0x58b).
My linux is Mandralke 9.0 (kernel 2.4.19-16mdk)

I load the modules usbcore and usb-uhci, and when I plug the device, they get the Descriptors from my device.

It appears the device in /proc/bus/usb/devices, but when it is referring the drivers, it appears drive=(none).
However, if I see the file /proc/bus/usb/drivers, it appears a new driver loaded, acm (Abstract Control Model). It happens the same if I load drivers before (CDCEther, kaweth,acm,usbnet,usbdnet,pegasus...)

My problem is that when I do ifconfig eth0 192.168.0.1
it happens an error (unknown interface eth0)
What is my mistake?
Have I forgoten any stage or do I need to develop a new Linux Driver ??

Please, help me !!
Thanks in advance
