Programming Interface — RO. A value of 20h indicates that this USB High-speed Host Controller
conforms to the EHCI Specification.
Sub Class Code — RO. A value of 03h indicates that this is a Universal Serial Bus Host Controller.
Base Class Code — RO. A value of 0Ch indicates that this is a Serial Bus controller.
Master Latency Timer Count (MLTC) — RO. Hardwired to 00h. Because the USB EHCI controller is
internally implemented with arbitration via hub interface (and not PCI), it does not need a master
latency timer.
