>From what I can see on the schematic, there is no way to power a USB device plugged into the BBAI USB Type-C socket, there is no path to switch +5V power to the Type-C socket VBUS.
You would need some sort of adapter or hub with power to supply your device (and the BBAI see below). The BBAI needs power from either USB Type-C or (+5V) P9.5, P9.6 and (0V) P9.1, P9.2. The USB2 can supply power to a device.
