HC_MAX_C_BP
Hub Controller Max Current Bus-Powered: the value in 2 mA increments that
the hub consumes from an upstream port (VBUS) when operating as a bus-
powered hub. This value will include the hub silicon along with the combined
power consumption (from VBUS) of all associated circuitry on the board.
Note:
This value will not include the power consumption of a permanently
attached peripheral if the hub is configured as a compound device.
A value of 50 (decimal) would indicate 100 mA, which is the default value.
