I am a first time user of Avnet attempting to get my Att lot starter kit (second generation) working.  I followed the instruction in tutorial 1 uisng ubuntu 16.10.  everything went as advertised except adb devices returns WNC_ADB no permissions.  what does this mean. 

Also, there is a flashing yellow light on the device, Im told to make sure the device is configured for the correct APN,  how do I do that?
