UsbBulkInPipe class

Applies to Windows only

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


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

Attributes

[DualApiPartition()]
[MarshalingBehavior(Agile)]
[Version(0x06030000)]

Members

The UsbBulkInPipe class has these types of members:

Methods

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

MethodDescription
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.

PropertyAccess typeDescription

EndpointDescriptor

Read-onlyGets the object that represents endpoint descriptor associated with the USB bulk IN endpoint.

InputStream

Read-onlyInput stream that stores the data that the bulk IN pipe received from the endpoint.

MaxTransferSizeBytes

Read-onlyGets the maximum number of bytes that can be read from the bulk IN pipe in a single transfer.

ReadOptions

Read/writeGets 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);
