UsbBulkInPipe class

Represents the pipe that the underlying USB driver opens to communicate with a USB bulk IN endpoint of the device. The app can get an input stream from the pipe and access data is being read from the endpoint.

Syntax

JavaScript

C++


var usbBulkInPipe = Windows.Devices.Usb.UsbBulkinEndpointDescriptor.Pipe;

Attributes

[DualApiPartition()]

[MarshalingBehavior(Agile)]

[Version(0x06030000)]

Properties

Methods

The UsbBulkInPipe class has these methods. With C#, Visual Basic, and C++, it also inherits methods from the Object class.

Method	Description
ClearStallAsync	Starts an asynchronous operation to clear a stall condition (endpoint halt) on the USB bulk IN endpoint that is associated with the pipe.
FlushBuffer	Discards any data that is cached in the bulk IN pipe.

Properties

The UsbBulkInPipe class has these properties.

Property	Access type	Description
EndpointDescriptor	Read-only	Gets the object that represents endpoint descriptor associated with the USB bulk IN endpoint.
InputStream	Read-only	Input stream that stores the data that the bulk IN pipe received from the endpoint.
MaxTransferSizeBytes	Read-only	Gets the maximum number of bytes that can be read from the bulk IN pipe in a single transfer.
ReadOptions	Read/write	Gets or sets configuration flags that controls the behavior of the pipe that reads data from a USB bulk IN endpoint.

Remarks

This code example shows how to read data from a bulk IN pipe. The example assumes that the app has previously obtained the UsbDevice object.

UsbDevice device;
UInt32 readLen = 8;

// Get the UsbDevice object. Not shown.

...
            
UsbBulkInPipe bulkIn = device.DefaultInterface.BulkInPipes[0];

DataReader reader = new DataReader(bulkIn.InputStream);
            
await reader.LoadAsync(readLen);
            
UInt64 data = reader.ReadUInt64();
            
ShowData(data);
