Self- or Bus-Power: Selects between self- and bus-powered operation.
The hub is either self-powered (draws less than 2 mA of upstream bus
power) or bus-powered (limited to a 100 mA maximum of upstream power
prior to being configured by the host controller).
When configured as a bus-powered device, the SMSC device consumes
less than 100 mA of current prior to being configured. After configuration, the
bus-powered SMSC device (along with all associated device circuitry, any
embedded devices if part of a compound device, and 100 mA per externally
available downstream port) must consume no more than 500 mA of
upstream VBUS current. The current consumption is system dependent, and
the OEM must ensure that the USB 2.0 Specification is not violated.
When configured as a self-powered device, <1 mA of upstream VBUS
current is consumed and all ports are available, with each port being capable
of sourcing 500 mA of current.
80 = Bus-powered operation (default)
C0 = Self-powered operation
A0 = Bus-powered operation with remote wake-up
E0 = Self-powered operation with remote wake-up
USB Max Power per the USB 2.0 Specification. Do NOT set this value
greater than 100 mA.
