Thom, mine shows up (listed as XT1080). My old device was a Droid 3; if I click that in ADM, it lists the Maxx.
You may need to update Google Play Services. Check the play store for updates (if you haven't already) and hopefully the new play services installs. If you see Android Device Manager in the Google Settings app, I'd think you'd be all set.
I noticed that Motorola also has a lost device service. After you activate it on the phone, you can go to https://motorola-global-portal.custhelp.com/app/home
and sign in in the upper right and follow the prompts to add your device.
