ucxroothub.h header
This header is used by usbref. For more information, see:
ucxroothub.h contains the following programming interfaces:
Functions
| UCX_ROOTHUB_CONFIG_INIT_WITH_CONTROL_URB_HANDLER Learn more about the UCX_ROOTHUB_CONFIG_INIT_WITH_CONTROL_URB_HANDLER function. |
| UcxRootHubCreate Learn more about the UcxRootHubCreate function. |
| UcxRootHubPortChanged Notifies UCX about a new port change event on the host controller. |
Callback functions
| EVT_UCX_ROOTHUB_CONTROL_URB The client driver uses this callback type to implement handlers that UCX calls when it receives feature control requests on the USB hub. |
| EVT_UCX_ROOTHUB_GET_20PORT_INFO The client driver's implementation that UCX calls when it receives a request for information about USB 2.0 ports on the root hub. |
| EVT_UCX_ROOTHUB_GET_30PORT_INFO The client driver's implementation that UCX calls when it receives a request for information about USB 3.0 ports on the root hub. |
| EVT_UCX_ROOTHUB_GET_INFO The client driver's implementation that UCX calls when it receives a request for information about the root hub. |
| EVT_UCX_ROOTHUB_INTERRUPT_TX The client driver's implementation that UCX calls when it receives a request for information about changed ports. |
Structures
| CONTROLLER_USB_20_HARDWARE_LPM_FLAGS Describes supported protocol capabilities for Link Power Management (LPM) in as defined the USB 2.0 specification. |
| HUB_INFO_FROM_PARENT Describes information about a hub from its parent device. |
| PARENT_HUB_FLAGS This structure is used by the HUB_INFO_FROM_PARENT structure to get hub information from the parent. |
| ROOTHUB_20PORT_INFO Provides information about a USB 2.0 root hub port. This structure is passed by UCX in the EVT_UCX_ROOTHUB_GET_20PORT_INFO callback function. |
| ROOTHUB_20PORTS_INFO This structure that has an array of 2.0 ports supported by the root hub. This structure is provided by UCX in a framework request in the EVT_UCX_ROOTHUB_GET_20PORT_INFO callback function. |
| ROOTHUB_30PORT_INFO Provides information about a USB 3.0 root hub port. This structure is passed by UCX in the EVT_UCX_ROOTHUB_GET_30PORT_INFO callback function. |
| ROOTHUB_30PORT_INFO_EX Provides extended USB 3.0 port information about speed. |
| ROOTHUB_30PORTS_INFO Provides information about USB 3.0 root hub ports. This structure is passed by UCX in the EVT_UCX_ROOTHUB_GET_30PORT_INFO callback function. |
| ROOTHUB_INFO Provides information about a USB root hub. This structure is passed by UCX in the EVT_UCX_ROOTHUB_GET_INFO callback function. |
| UCX_ROOTHUB_CONFIG Contains pointers to event callback functions for creating the root hub by calling UcxRootHubCreate. Initialize this structure by calling UCX_ROOTHUB_CONFIG_INIT initialization function (see Ucxclass.h). |
Enumerations
| CONTROLLER_TYPE This enumeration specifies if the USB host controller is an eXtensible Host Controller Interface (xHCI) controller. |
| TRISTATE The TRISTATE enumeration indicates generic state values for true or false. |
