Gadget II Not working. Firmware update wanted.

Question

I'm attempting to set up a Gadget II. 
 Initially i had a solid green led indicating a successful USB connection, but I had no DMX output (running from either an iMac 10.13.3 OS or a Windows 10 PC) via ETCNomad. I have the current version of Nomad. 
 I attempted to update firmware and drivers via the PC but couldn't get it to update to the 1.4.2 version. In the maintenance dialog for I/O Firmware Upgrade it never recognized the Gadget when selecting that option. The recognized devices window immediately below that button would recognize it, but when updating via that method it wouldn't change any versions or seem to actually update anything. It would then be in Bootloader as a drive. If I unlplugged and replugged as well as restarted Nomad it would bring me back to where I started. 
 Eventually I tried a trick of copying the proper firmware (the older 1.0.0.something, not the new 1.4.2 version that I've downloaded) into the Bootloader drive. This seemed to work and the LED blinked red for some time. Eventually (about 20 minutes) of this and I tried running the update methods from the how-to that comes with the IO firmware (1.4.2). No luck. 
 At this point, the Gadget II now has a solid red light (indicating it's not connecting at all?) and is not recognized anywhere on either computer. I've tried reboots, unplugging the Gadget II (and letting it sit for a few minutes) and about everything else I can think of. 
 Do I have a dud, or is there some simple trick I'm missing?

To update folks, ETC tech support is stellar, they call back on questions (which is likely why the forums don't have a ton of information on some things):

I had the Gadget II showing up in the I/O section of the Nomad software, and it shows up when I run System Report (via the apple in the upper left hand of any Mac) as a USB Console I/O HS (the dongle is Sentinal HL). We also had confirmed connection inside of a Primary show. Holding Tab and pressing 99 brings up diagnostics, which showed connecting/disconnecting when plugging and unplugging the Gadget II.

The end fix was under the Eos Family Welcome Screen - Settings - Local I/O. We need both "Enable" and "Default Output Protocol" checked. This enables the DMX output by default in the Patch settings, which was our easy fix. Something that should normally be defaulted (but might not be re-set during a reload of the software, which we did), but which leaves the patch without DMX by default.

So, easy fix! One check mark! Thanks for the phone assistance ETC!
