Figure 22. Typical Six-Port USB Host/Self-Powered Hub
BPHs obtain all power from upstream ports and often contain an embedded function. The hubs are required to
power up with less than one unit load. The BPH usually has one embedded function, and power is always
available to the controller of the hub. If the embedded function and hub require more than 100 mA on power up,
the power to the embedded function may need to be kept off until enumeration is completed. This can be
accomplished by removing power or by shutting off the clock to the embedded function. Power switching the
embedded function is not necessary if the aggregate power draw for the function and controller is less than one
unit load. The total current drawn by the bus-powered device is the sum of the current to the controller, the
embedded function, and the downstream ports, and it is limited to 500 mA from an upstream port.
