UVC Watchdog

#!/usr/bin/env expect

# Description:
#   This tool aims to achieve the "auto-start script" upon device reboot or power lost,
#   since there's no ready auto-start hook at post-init stage for UVC

# Installation:
#   Install "expect", "netcat" and "sshpass" first if your Linux distribution don't have it ready
#   $ sudo apt-get install expect sshpass netcat
