9.2.2.2.1 Low-Power Bus-Powered and High-Power Bus-Powered Functions
Both low-power and high-power bus-powered functions obtain all power from upstream ports; low-power functions always draw less than 100 mA; high-power functions must draw less than 100 mA at power up and can draw up to 500 mA after enumeration. If the load of the function is more than the parallel combination of 44 ? and 10 μF at power up, the device must implement inrush current limiting (see Figure 9-17).
