Which, for a compliant USB2 socket, provides a maximum of 500mA. Most
of that is used by the SoC and support (I think I read that the peak during
boot is around 400mA), so the amount available on the 3.3V pins will likely
be less than the 250mA (which should be available if using a 5V barrel jack
power supply). The main 5V pins are disabled under USB power.
