USB networking with Ubuntu 9.04

[Eric Olson]

I copied Sander's exact lines into /etc/network/interfaces (I changed 
eth2 to usb0 -- I don't know if that matters) on my ubuntu 9.04 laptop 
and it's working for me.  I have plugged and unplugged the cable a 
couple times and no longer have to run my manual script each time.

Thanks!
Eric
