HC_MAX_C_BP
Hub Controller Max Current Bus-Powered: Value in 2mA 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. This
value will NOT include the power consumption of a permanently attached
peripheral if the hub is configured as a compound device.

Power On Time: The length of time that is takes (in 2 ms intervals) from the
time the host initiated power-on sequence begins on a port until power is good
on that port. System software uses this value to determine how long to wait
before accessing a powered-on port.
