_UCX_ROOTHUB_CONFIG structure

Description

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).

Members

The size in bytes of this structure.

`NumberOfPresentedControlUrbCallbacks`

The number of control requests sent to the default endpoint.

`EvtRootHubClearHubFeature`

A pointer to the EVT_UCX_ROOTHUB_CONTROL_URB callback function.

`EvtRootHubClearPortFeature`

A pointer to the EVT_UCX_ROOTHUB_CONTROL_URB callback function.

`EvtRootHubGetHubStatus`

A pointer to the EVT_UCX_ROOTHUB_CONTROL_URB callback function.

`EvtRootHubGetPortStatus`

A pointer to the EVT_UCX_ROOTHUB_CONTROL_URB callback function.

`EvtRootHubSetHubFeature`

A pointer to the EVT_UCX_ROOTHUB_CONTROL_URB callback function.

`EvtRootHubSetPortFeature`

A pointer to the EVT_UCX_ROOTHUB_CONTROL_URB callback function.

`EvtRootHubGetPortErrorCount`

A pointer to the EVT_UCX_ROOTHUB_CONTROL_URB callback function.

`EvtRootHubControlUrb`

A pointer to the EVT_UCX_ROOTHUB_CONTROL_URB callback function.

`EvtRootHubInterruptTx`

A pointer to the EVT_UCX_ROOTHUB_INTERRUPT_TX callback function.

`EvtRootHubGetInfo`

A pointer to the EVT_UCX_ROOTHUB_GET_INFO callback function.

`EvtRootHubGet20PortInfo`

A pointer to the EVT_UCX_ROOTHUB_GET_20PORT_INFO callback function.

`EvtRootHubGet30PortInfo`

A pointer to the EVT_UCX_ROOTHUB_GET_30PORT_INFO callback function.

`WdfRequestAttributes`
