+    ESP8266 that have an onboard USB chip (e.g. D1 mini) one the chips' control lines is connected to the RST pin. This enables the flasher can reboot the ESP when required. This may interfere with deep sleep on some devices and prevent the ESP from waking when it's powered through its USB connector. Powering the ESP from a separate 3.3V source connected to the 3.3V pin and GND will solve this issue. In these cases using a USB to TTL adapter will allow you to log ESP activity.
