Orange Pi Zero board features a USB OTG port, which has a ID pin, and can be used to power up the board. However, even if the board is powered via +5V pin in GPIO/expansion headers, the VBUS in the OTG port cannot be powered up, thus it's impossible to use it in host mode with simple OTG cables. Add support for it in peripheral mode. If someone really want to use it in host mode, the mode of PHY can be switch via sysfs, then use a powered USB OTG cable or powered USB HUB to power up external USB devices.
