10.3 HC Root Hub registers
All registers included in this partition are dedicated to the USB Root Hub, which is an
integral part of the HC although it is functionally a separate entity. The Host Controller
Driver (HCD) emulates USBD accesses to the Root Hub via a register interface. The
HCD maintains many USB-defined hub features that are not required to be supported
in hardware. For example, the Hub’s Device, Configuration, Interface, Endpoint
Descriptors, as well as some static fields of the Class Descriptor, are maintained only
in the HCD. The HCD also maintains and decodes the Root Hub’s device address as
well as other minor operations more suited for software than for hardware.
The Root Hub registers were developed to match the bit organization and operation
of typical hubs found in the system.
Four 32-bit registers have been defined:
HcRhDescriptorA
HcRhDescriptorB
HcRhStatus
HcRhPortStatus[1:NDP]
Each register is read and written as a DWORD. These registers are only written
during initialization to correspond with the system implementation. The
HcRhDescriptorA and HcRhDescriptorB registers are writeable regardless of the
HC’s USB states. HcRhStatus and HcRhPortStatus are writeable during the
USBOperational state only.

LSThreshold:
Contains a value that is compared to the
FrameRemaining field before a low-speed transaction is initiated.
The transaction is started only if FrameRemaining
this field. The
value is calculated by the HCD, which considers transmission and
set-up overhead. Default value: 1576 (628H)
