On Linux ethernet devices don't get device nodes, so you won't see any network
devices in /dev. Also, ifconfig will only show you configured ethernet devices
(unless you ask it to show you them all); since your new USB device isn't
configured, it's not showing up on the list.

What you need to do is:

ifconfig -a

...which will tell you the name of the network device, and then:

ifconfig [name] up [ipaddress] netmask [netmask] gw [gateway]

...to configure it. From there it ought to work, though you may need to tweak
the routing table (use the 'route' command) and the DNS setup
(/etc/resolv.conf) first.
