Wireshark Macbook Air USB assistance

[John C <johnc73 () gmail com>]

I just installed Wireshark 1.2.4 on my MacBook Air, and I need some
assistance in getting the USB Ethernet Interface to be recognized to do
captures from. Does anyone know how to get the USB ethernet interface
to show up in the selectable capture interface list so you can get
ethernet captures from the USB interface ? Neither my Airport nor my USB
port are showing up as capture interfaces (I have no interfaces to select).
My ifconfig -a output is

61-31-22-173:.wireshark-etc johnc73$ ifconfig -a
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet6 ::1 prefixlen 128
