Usb​Bulk​Out​Pipe Usb​Bulk​Out​Pipe Usb​Bulk​Out​Pipe Usb​Bulk​Out​Pipe Class

Definition

Represents the pipe that the underlying USB driver opens to communicate with a USB bulk OUT endpoint of the device. The object provides access to an output stream to which the app can write data to send to the endpoint.

Properties

EndpointDescriptor EndpointDescriptor EndpointDescriptor EndpointDescriptor

Gets the object that represents the endpoint descriptor associated with the USB bulk OUT endpoint.

public : UsbBulkOutEndpointDescriptor EndpointDescriptor { get; }public UsbBulkOutEndpointDescriptor EndpointDescriptor { get; }Public ReadOnly Property EndpointDescriptor As UsbBulkOutEndpointDescriptor// You can use this property in JavaScript.
Value
UsbBulkOutEndpointDescriptor UsbBulkOutEndpointDescriptor UsbBulkOutEndpointDescriptor UsbBulkOutEndpointDescriptor

A UsbBulkOutEndpointDescriptor that represents the endpoint descriptor associated with the USB bulk OUT endpoint.

OutputStream OutputStream OutputStream OutputStream

Gets an output stream to which the app can write data to send to the endpoint.

public : IOutputStream OutputStream { get; }public IOutputStream OutputStream { get; }Public ReadOnly Property OutputStream As IOutputStream// You can use this property in JavaScript.
Value
IOutputStream IOutputStream IOutputStream IOutputStream

The output steam that contains the transfer data.

Remarks

To write data, first get the output stream from the pipe by using OutputStream property and then use the DataWriter object to write the actual buffer.

    Windows::Storage::Streams::Buffer^ buffer = ref new Windows::Storage::Streams::Buffer(TRANSFER_SIZE);  

    buffer->Length = TRANSFER_SIZE;  

    auto stream = DeviceList::Current->Fx2Device->Configuration->UsbInterfaces->GetAt(0)->BulkOutPipes->GetAt(0)->OutputStream;  

    Windows::Storage::Streams::DataWriter^ writer = ref new Windows::Storage::Streams::DataWriter(stream);  

    writer->WriteBuffer(buffer);  


    });  

WriteOptions WriteOptions WriteOptions WriteOptions

Gets or sets configuration flags that controls the behavior of the pipe that writes data to a USB bulk IN endpoint.

public : UsbWriteOptions WriteOptions { get; set; }public UsbWriteOptions WriteOptions { get; set; }Public ReadWrite Property WriteOptions As UsbWriteOptions// You can use this property in JavaScript.
Value
UsbWriteOptions UsbWriteOptions UsbWriteOptions UsbWriteOptions

A UsbWriteOptions constant that indicates the pipe policy.

Methods

ClearStallAsync() ClearStallAsync() ClearStallAsync() ClearStallAsync()

Starts an asynchronous operation to clear a stall condition (endpoint halt) on the USB bulk OUT endpoint that is associated with the pipe.

public : IAsyncAction ClearStallAsync()public IAsyncAction ClearStallAsync()Public Function ClearStallAsync() As IAsyncAction// You can use this method in JavaScript.
Returns

An IAsyncAction object that is used to control the asynchronous operation.
