Hello

I am using the mangoH green board.

it has a virtual Ethernet port over USB called ecm0, using the serial terminal I can see that the IP address is 192.168.2.2

however when connecting the device to my PC via USB (ubuntu 16.04) I can not ping the device, nor ssh it

using the developer studio I can not access the device

please advice
