USB software implementation on Esp32

[Deouss]

I found a full implementation a low-speed USB device but for Atmel’s AVR microcontrollers.
It is fully opensourced and has examples however it is rather not compatible with Xtensa cpu.
Maybe someone finds it interesting and even converts the code to work with Esp.
