For the OHCI Host Controller, these registers are divided into two types: one set of
operational registers for the USB operation and one set of legacy support registers for the
legacy keyboard and mouse operation.
For the enhanced Host Controller, there are two types of registers: one set of read-only
capability registers and one set of read and write operational registers.
OHCI HCDs must communicate with these registers to implement USB data transfers.
Based on their functions, these registers are classified into four partitions:
