The GTA02 (I'm presuming that's what it is) has an RNDIS interface at
configuration 0 and CDCE is at configuration 1 so you'll need to run:

usbconfig -u 1 -a 2 set_config 1

The parameters to -a and -u will vary depending on which ugen device it
gets detected as.  Mine's often ugen3.2 but changes depending on which
other USB devices I've plugged in.

You should then see the kernel messages relating to cdce and be able to
assign an IP address to ue0 (what was cdce0 in 7.x is now ue0).
