UcxRootHubPortChanged function (ucxroothub.h)
Notifies UCX about a new port change event on the host controller.
Syntax
void UcxRootHubPortChanged(
[in] UCXROOTHUB UcxRootHub
);
Parameters
[in] UcxRootHub
A handle to the root hub object. The client driver retrieved the handle in a previous call to UcxRootHubCreate.
Return value
None
Remarks
This method causes interrupt transfers to be sent to the host controller. UCX invokes the client driver's implementation of the EVT_UCX_ROOTHUB_INTERRUPT_TX event callback.
