Very often I need wait 2..3.. or 5 minutes until Arduino Ide find com port for Leonardo board. I have 1.6.4 Arduino IDE.

About robot freezing. Tried with three separate batteries - one for motors 11.1V lipo and second 5V stabilized for Arduino and third 3.3V stabilized for MPU6050 and ESP8266. Conclusion - there is no problems with Batteries and power lines because robot freeze anyway. Robot work while it is horizontal. When I slowly rise it up, it show angle adjusted until motors start. Debug 1 show angle until start motor then robot freeze. Sometime motors run 10 - 20secons and respond to gyro angles, then freeze and show FIFO Reset. After several FIFO Reset prints (sometime 1, sometime 15+) serial stop too. With motor disconnected work fine and not freeze - serial monitor not show any errors. I cant understand how can motor connection influate Arduino board and freeze them with separate power lines and batteries. I have soldered 220uF capacitors on all power lines. Some 0.1uF capacitors on stepper driver power.
I checked fifoCount value after freezing - it is all time zero "0". Looks like Stepper motor block I2C or MPU.
