Not the same problem, but I also found [unexpected (at least for me) interaction between USB Serial and I2C on a Core](https://community.particle.io/t/serial-print-s-to-unconnected-usb-corrupting-i2c/12414). Workaround was to delete Serial.print() statements, but I don’t have an explanation for what was happening yet.
