Seems I was confused by the GPIO pin number mapping. pin_usb_host_en1
is used to control the USB2 port, while pin_usb_host_en0 is for USB3
port. So I should say:

My testing shows that only pin_usb_host_en1 is needed to turn on the
power on the USB2 (upper white) port. The USB3 (bottom blue) port
power is turned on by default.
