Your best bet is to look at the circuit, Stan.
I think it might be a double diode. One feed comes from the USB 5V, one feed comes from VIN and the common cathode goes to VOUT and the input of the 3V3 regulator. Connected like this you can never power the USB supply from the module. I think putting power the other way from a powered hub might work as you are still supplying the 3V3 regulator at the same time as any USB devices, just in the opposite direction.
