Looks like the interface we're looking for, although the MAC address is
different from what you read on the device screen (08:BD:43:34:15:9A).

Now you can try to set the interface up, run a DHCP client on it
(dhclient, pump, dhcpcd, udhcpc...) and check what happens.

Note : according to what you read on the device screen, it uses an IP
address in the same range so you may need to set a different subnet on
the LAN interface.

Confirmed by the kernel log.

Really ? Even though the rndis_host module was automatically loaded ?
On my box it returns "rndis_host" for the first alias returned by the
previous command :

modprobe -R usb:v0846p68E1dFFFFdc02dsc00dp00icE0isc01ip03
rndis_host
