For the OHCI Host Controller, there are only operational registers for the USB 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 need to communicate with these registers to implement USB data transfers.
Based on their functions, these registers are classified into four partitions:
•
