@legolas : you know that physically eth1 is a wireless device. However, Linux sees that the iwconfig commands do not apply to this device, which means that probably the wifi extensions for that device are not loaded.
What do you see in /var/log/syslog about eth0 ? what does "usbview" show ?
You know, my goal is not to see if you are dumb or not, our goal here is to see how we can make a Linux diagnostic in order to help you.
