EVT_UCX_USBDEVICE_ADDRESS callback function

The client driver's implementation that UCX calls to address the USB device.

Syntax

EVT_UCX_USBDEVICE_ADDRESS EvtUcxUsbdeviceAddress;

void EvtUcxUsbdeviceAddress(
  UCXCONTROLLER UcxController,
  WDFREQUEST Request
)
{...}

Parameters

UcxController

A handle to the UCX controller that the client driver received in a previous call to the UcxControllerCreate method.

Request

A structure of type USBDEVICE_ADDRESS.

Return Value

This callback function does not return a value.

Remarks

The UCX client driver registers this callback function with the USB host controller extension (UCX) by calling the UcxUsbDeviceCreate method.

The client driver returns completion status in Request. The driver can complete the WDFREQUEST asynchronously.

Examples

VOID
UsbDevice_EvtUcxUsbDeviceAddress(
    UCXCONTROLLER      UcxController,
    WDFREQUEST         Request
)

{ UNREFERENCED_PARAMETER(UcxController);

DbgTrace(TL_INFO, UsbDevice, "UsbDevice_EvtUcxUsbDeviceAddress");

WDF_REQUEST_PARAMETERS_INIT(&wdfRequestParams);
WdfRequestGetParameters(WdfRequest, &wdfRequestParams);

usbDeviceAddress = (PUSBDEVICE_ADDRESS)wdfRequestParams.Parameters.Others.Arg1;
...

WdfRequestComplete(Request, STATUS_SUCCESS);

}
