Perso, mon interface était usb0, et il n'y avait pas de
allow-auto. D'autre part, j'utilisais le script joint avec dans
/etc/network/interfaces les choses suivantes:

# The Usb interface
allow-hotplug usb0
iface usb0 inet static
      address 192.168.0.200
      netmask 255.255.255.0
      network 192.168.0.0
      broadcast 192.168.0.255
      post-up /etc/network/freerunner start
      pre-down /etc/network/freerunner stop
