Alex, please sudo lshw -c network and post output. On my Trusty system, the card showed up as there but disabled - finding it with lshw -c network allowed me to ifconfig up the device and truck right on from there with no issues (though with a funny devicename - p1p1 instead of eth0, but who cares, really).
