As of today I have finished my first working prototype, I have implemented all functions of the USBValve and added the overvoltage detection and remediation. I based my design in the TPS2514A (Charging Port Controller) and TPD2E001 (Electrostatic Discharge Protection).

Because of the cost of the "specialty" hardware I design an module to reuse in case of need. I'll upload it later.

I wanted to add more functions to the firmware like Device ID detection, USB payloads debugging and more.

Also I'll have to add more hardware in the future like an EEPROM or flash exclusively for the file system so I can expand the firmware without bugs and missing space.
