Preface

I owe my very rapid learning journey in the world of ConfigFs to several key sources which aren't necessarily relevant to this result, but I feel deserve a mention anyway.

• This really demystified configfs for me, and stopped me being afraid of it: http://events.linuxfoundation.org/sites/events/files/slides/USB%20Gadget%20Configfs%20API_0.pdf
• I borrowed heavily from this Mindstorms EV3 script: https://github.com/ev3dev/ev3-systemd/blob/ev3dev-jessie/scripts/ev3-usb.sh
• Desperately trawled this thread for answers: https://answers.microsoft.com/en-us/windows/forum/windows_10-networking-winpc/windows-10-vs-remote-ndis-ethernet-usbgadget-not/cb30520a-753c-4219-b908-ad3d45590447?auth=1
• This guide is handy: http://irq5.io/2016/12/22/raspberry-pi-zero-as-multiple-usb-gadgets/

# Actually gets Google Home's bluetooth to connect reliably on Windows 10.
# Unpairs Windows AND Google Home using MAC address, then sets everything up for a one-click connection.

# * Prevents Google Home from getting stuck paried using bttool, which is apparently the only way to fix that?
# * Uses some code from Stack Overflow to get the IP from the MAC address so you don't have to dick around with static IP's
# * Connects reliably by repairing bluetooth on Google Home using the "secret" REST API (https://rithvikvibhu.github.io/GHLocalApi)
# * Opens control legacy panel after setting up Google for pairing

#
# Needs btpair installed first, get it from http://bluetoothinstaller.com/bluetooth-command-line-tools/
