Public bug reported:

I'm trying to install hardy on an old laptop that does not have a
network 10/100 card.

I can connect to my cable modem using a usb cable instead of the
ethernet cable and it works fine on a running ubuntu.  It configures the
network using the cdc-ether driver, as follows:

paul :~$ dmesg | grep -i eth

This works fine on an installed ubuntu, but when I boot the installer to
do an installation on the older computer, nothing is set up.  I had the
cable modem usb cable hooked up before boot, but it was not detected.

I also tried going into Alt-F2 console and setting it up manually, but
ifconfig showed nothing but "lo".  And, there is not cdc-ether module
that I could try to load using modprobe.

How am I supposed to set up the network on the installer?
