EVT_UCX_USBDEVICE_ADDRESS callback function

Description

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

Parameters

UcxController [in]

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

Request [in]

A structure of type USBDEVICE_ADDRESS.

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);
}
