Conect ESP with USB

Hardware
1

Hello Dear Friends.
I’m planning to implement a “prototype industrial control” with HA.

The idea is to run a server (MiniPC or Pi4) inside a cabinet. All the ESPs (NodeMCU and D1 Mini, ESP8266, and ESP32 )will be really close to close to the server. Maybe even power them through server USBs

Is it any way to integrate them via the USB cable? I investigated but I couldn´t find anything with ESPHome or Tasmota.

With the same idea, and as a lot of industrial sensors use ModBUS, the idea is to use a USB-RS485 adapter to build a ModBUS Network

Do you have any ideas or suggestions?
All ideas are welcome.

In theory you could use a USB hub, but USB is not really an “industrial” network whereas modbus was developed as an industrial network long before HA. I have not done any Esp USB communications and not even sure it is possible. For an ESP device Wifi is likely the best route. ESP devices can certainly be powered off the USB but typically use Bluetooth or WiFi for their communications. There may also be an option to use serial but again I am not certain on this.
