Least Significant Byte of the Product ID. This is a 16-bit value that the vendor
can assign that uniquely identifies this particular product.
Self- or Bus-Power: Selects between self- and bus-powered operation.
The hub is either self-powered (draws less than 2 mA) or bus-powered
(limited to 100 mA maximum power prior to being configured by the host
controller).
When configured as a bus-powered device, the SMSC hub consumes less
than 100 mA of current prior to being configured. After configuration, the bus-
powered SMSC hub (along with all associated hub 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 current. The
current consumption is system dependent, and the OEM must ensure that
the USB 2.0 specifications are not violated.
When configured as a self-powered device, <1 mA of current is consumed
and all ports are available, with each port being capable of sourcing 500 mA
of current.
‘0’ = Bus-powered operation
‘1’ = Self-powered operation
Reserved
Hi-Speed Disable: Disables the capability to attach as either a Hi-/Full-Speed
device, and forces attachment as Full-Speed only (i.e. no Hi-Speed support).
‘0’ = Hi-/Full-Speed
‘1’ = Full-Speed-Only (Hi-Speed disabled!)
Most Significant Byte of the Product ID. This is a 16-bit value that the vendor
can assign that uniquely identifies this particular product.
Least Significant Byte of the Device ID. This is a 16-bit device release
number in BCD (binary coded decimal) format.
Most Significant Byte of the Device ID. This is a 16-bit device release
number in BCD format.
