UFX_DEVICE_CALLBACKS structure (ufxclient.h)

The UFX_DEVICE_CALLBACKS structure is used to define then event callback functions supported by the client driver.

Members

Size

The size of the UFX_DEVICE_CALLBACKS structure.

EvtDeviceHostConnect

EvtDeviceHostDisconnect

A pointer to the client driver’s EVT_UFX_DEVICE_HOST_DISCONNECT callback routine.

EvtDeviceAddressed

A pointer to the client driver’s EVT_UFX_DEVICE_ADDRESSED callback routine.

EvtDeviceEndpointAdd

A pointer to the client driver’s EVT_UFX_DEVICE_ENDPOINT_ADD callback routine.

EvtDeviceDefaultEndpointAdd

A pointer to the client driver’s EVT_UFX_DEVICE_DEFAULT_ENDPOINT_ADD callback routine.

EvtDeviceUsbStateChange

A pointer to the client driver’s EVT_UFX_DEVICE_USB_STATE_CHANGE callback routine.

EvtDevicePortChange

A pointer to the client driver’s EVT_UFX_DEVICE_PORT_CHANGE callback routine.

EvtDevicePortDetect

A pointer to the client driver’s EVT_UFX_DEVICE_PORT_DETECT callback routine.

EvtDeviceRemoteWakeupSignal

A pointer to the client driver’s EVT_UFX_DEVICE_REMOTE_WAKEUP_SIGNAL callback routine.

EvtDeviceControllerReset

A pointer to the client driver’s EVT_UFX_DEVICE_CONTROLLER_RESET callback routine.

EvtDeviceTestModeSet

A pointer to the client driver’s EVT_UFX_DEVICE_TEST_MODE_SET callback routine.

EvtDeviceTestHook

Reserved. Should be set to NULL.

EvtDeviceSuperSpeedPowerFeature

A pointer to the client driver’s EVT_UFX_DEVICE_SUPER_SPEED_POWER_FEATURE callback routine.

EvtDeviceProprietaryChargerDetect

A pointer to the client driver’s EVT_UFX_DEVICE_DETECT_PROPRIETARY_CHARGER callback routine.

EvtDeviceProprietaryChargerSetProperty

A pointer to the client driver’s EVT_UFX_DEVICE_PROPRIETARY_CHARGER_SET_PROPERTY callback routine.

EvtDeviceProprietaryChargerReset

A pointer to the client driver’s EVT_UFX_DEVICE_PROPRIETARY_CHARGER_RESET callback routine.

Remarks

The client driver shall use the UFX_DEVICE_CALLBACKS_INIT macro to initialize the UFX_DEVICE_CALLBACKS structure, and then shall set fields of structure to the appropriate event callback routines prior to calling the UfxDeviceCreate export function.
