What do we need for enabling the bootloader to flash over USB? See AN2606 p. 26. screen shot 2016-07-15 at 23 38 52

Comment from @electrokean

STM32F103 doesn't have built in USB DFU bootloader, so it would be dependant on a separate bootloader like https://github.com/rogerclarkmelbourne/STM32duino-bootloader See the notes there in README.md as there are a few implementation options for the disconnect feature

The STM32F103 does not have DFU, but there are a number of chips that are compatible with the physical board. I'd like to have any necessary hardware those chips would need.
