I would like to connect the Raspberry Pi Zero to my laptop using an ethernet cable without using the micro-USB port. Currently I can connect using ethernet cable through a micro-USB to RJ45 converter. I am using Putty and xming for the GUI. For our project we have a limitation of not using a powered USB hub and we need a UMTS stick for 3G connected all the time to the Rpi. Hence I cannot use it for ethernet connection. So is it possible to use the free micro HDMI port using a HDMI to Rj45 adaptor to connect an ethernet cable to Rpi Zero ?
