The Open Host Controller Interface (OpenHCI) Specification for the
Universal
Serial Bus is a register-level description of a Host Controller for the
Universal Serial Bus (USB) which in turn is described by the Universal Serial
Bus Specification, released by Intel Corp. The purpose of OpenHCI is to accelerate the acceptance of USB in the marketplace by promoting
the use of a common industry software/hardware interface. OpenHCI allows
multiple Host Controller vendors to design and sell Host Controllers with a
common software interface, freeing them from the burden of writing and
distributing software drivers. The design goal has been to balance the
complexity of the hardware and software so that OpenHCI is more than the
simplest possible Host Controller for USB yet not the most complex possible.
