With servo V4 connected that I was using successfully yesterday I now see,


2018-10-18 14:25:55,312 - Servod - INFO - Initializing interface 26 to ec3po_uart

when starting w/ 'sudo servod' and using 

$ equery k ec-utils
* Checking chromeos-base/ec-utils-0.0.1-r5121 ...
   7 out of 7 files passed

$ equery k hdctools
* Checking dev-util/hdctools-0.0.1-r871 ...
   718 out of 718 files passed

Will try ToT next and look more deeply at the ec3po_interface.py file after that.
