wda+UNtest+htmltestrunner运行的自动化脚本的时候老是出现'device port:8100 is not ready'

Start with the failing call in scripts/sgapp_home_userdefine_click.py and base/sg_action.py, then trace the connection through wda/requests_usbmux.py and wda/usbmux.py at the reported lines. Reproduce the WDA automation run and determine why device port 8100 is not ready; done means the setup reaches the WDA action without this connection error.
