Least Significant Byte of the Product ID. This is a 16-bit value that the vendor
can assign that uniquely identifies this particular product.
Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces
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 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 upstream VBUS
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 upstream VBUS
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!)
