Max Power Bus_Powered: Value in 2mA increments that the Hub consumes
from an upstream port (VBUS) when operating as a bus-powered hub. This
value includes the hub silicon along with the combined power consumption
(from VBUS) of all associated circuitry on the board. This value also includes
the power consumption of a permanently attached peripheral if the hub is
configured as a compound device, and the embedded peripheral reports 0mA
in its descriptors.
Hub Controller Max Current Self-Powered: Value in 2mA increments that the
Hub consumes from an upstream port (VBUS) when operating as a self-
powered hub. This value includes the hub silicon along with the combined
power consumption (from VBUS) of all associated circuitry on the board. This
value does NOT include the power consumption of a permanently attached
peripheral if the hub is configured as a compound device.
Note:
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.
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.
