BeagleBone Green does not load driver for UWN200 WiFi adaptor

My BBB Blacks seemed to find the UWN200 (Ralink - from LogicSupply) Wifi driver out of the box. Not so the BBB-Green from Seeed Studio (Linux version 3.8.13-bone71.1). I find lots of WiFi documentation, but all roads seem to just lead deeper into the swamp.



The "3.8.13-bone71.1" as a custom build so the modules aren't in the repo...
