The device path is part of the context structure and describes the location of the particular USB host controller in the system for which this register event will occur. This location is important because of the possible integration of several USB host controllers in a system.

EFI_USB_MMI_TYPE EFI_MM_USB_REGISTER_CONTEXT::Type

Describes whether this child handler will be invoked in response to a USB legacy emulation event, such as port-trap on the PS/2* keyboard control registers, or to a USB wake event, such as resumption from a sleep state.
