getting esp8266 NodeMCU to work over USB? about snap4arduino HOT 1 OPEN

Hi Raphaël ( @drzraf )
I guess everybody is using FirmataWifi with ESP8266... but you can play over serial USB.
Three tips:

• I have to add one line to StandardFirmata code, because pins 1 and 3 are the TX and RX pins so they have to be ignored or they will cause conflicts when using the USB serial connection
  The line is
  if (i == 1 || i == 3) continue;
  and it have to be added after

  for (byte i = 0; i < TOTAL_PINS; i++) {
    // pins with analog capability default to analog input
    // otherwise, pins default to digital output

• And you know, when you are connecting from Snap4Arduino (while it is trying to connect...) you have to press 'reset' button on your NodeMCU
• And I see (testing now for answering your question) that the disconnect action is not well configured for this board. Then, you have to re-plug your USB after a disconnection... to be able to reconnect.
