ENDPOINTS_CONFIGURE structure (ucxendpoint.h)
Describes endpoints to enable or disable endpoints. This structure is passed by UCX in the EVT_UCX_USBDEVICE_ENDPOINTS_CONFIGURE callback function.

Members
Header
A USBDEVICE_MGMT_HEADER structure that stores handles to the USB hub or device whose endpoints.
EndpointsToEnableCount
The number of endpoints to configure.
EndpointsToEnable
A pointer to the first endpoint handle in the array of endpoints to enable.
EndpointsToDisableCount
The number of endpoints to configure.
EndpointsToDisable
A pointer to the first endpoint handle in the array of endpoints to enable.
EndpointsEnabledAndUnchangedCount
The number of endpoints that were enabled and unchanged.
EndpointsEnabledAndUnchanged
A pointer to the first endpoint handle in the array of endpoints that have not been changed.
FailureFlags
The errors, if any, that might occur when attempting to configure endpoints for the USB device or hub.
ExitLatencyDelta
The Exit Latency Delta (ELD) value. For more information see section 4.6.6.1 of the eXtensible Host Controller Interface specification.
ConfigurationValue
The configuration number of the USB configuration that contains the endpoints.
InterfaceNumber
The interface number of the USB interface that contains the endpoints.
AlternateSetting
The setting number of the alternate setting that contains the endpoints.
Reserved1
Reserved2
