UsbInterruptInEndpointDescriptor UsbInterruptInEndpointDescriptor UsbInterruptInEndpointDescriptor UsbInterruptInEndpointDescriptor Class

Definition

The endpoint descriptor for a USB interrupt IN endpoint. The descriptor specifies the endpoint type, direction, number and also the maximum number of bytes that can be read from the endpoint, in a single transfer. The app can also get information about how often the host polls the endpoint for data.

Properties

EndpointNumber EndpointNumber EndpointNumber EndpointNumber

Gets the USB endpoint number of the interrupt IN endpoint.

public : byte EndpointNumber { get; }
public byte EndpointNumber { get; }
Public ReadOnly Property EndpointNumber As byte
var byte = usbInterruptInEndpointDescriptor.endpointNumber;
Value
byte byte byte byte

The endpoint number of the interrupt IN endpoint. That number is in Bit 3...0 of the bEndpointAddress field of an endpoint descriptor. For information, see Table 9-13 in the Universal Serial Bus Specification (version 2.0) or Table 9-18 in the Universal Serial Bus 3.0 Specification.

Interval Interval Interval Interval

Gets the poling interval of the USB interrupt endpoint.

public : TimeSpan Interval { get; }
public TimeSpan Interval { get; }
Public ReadOnly Property Interval As TimeSpan
var timeSpan = usbInterruptInEndpointDescriptor.interval;
Value
TimeSpan TimeSpan TimeSpan TimeSpan

The poling interval of the USB interrupt endpoint.

MaxPacketSize MaxPacketSize MaxPacketSize MaxPacketSize

Gets the maximum number of bytes that can be sent to or received (in a packet) from this endpoint.

public : unsigned int MaxPacketSize { get; }
public uint MaxPacketSize { get; }
Public ReadOnly Property MaxPacketSize As uint
var uint = usbInterruptInEndpointDescriptor.maxPacketSize;
Value
unsigned int uint uint uint

Indicates the maximum packet size of the endpoint. This value is the wMaxPacketSize field value of the endpoint descriptor. For information, see Table 9-13 in the Universal Serial Bus Specification (version 2.0) or Table 9-18 in the Universal Serial Bus 3.0 Specification.

Remarks

The MaxPacketSize property value does not necessarily indicate the number of bytes that will be read at a time, in one interval.

Pipe Pipe Pipe Pipe

Gets the object that represents the pipe that the host opens to communicate with the interrupt IN endpoint.

public : UsbInterruptInPipe Pipe { get; }
public UsbInterruptInPipe Pipe { get; }
Public ReadOnly Property Pipe As UsbInterruptInPipe
var usbInterruptInPipe = usbInterruptInEndpointDescriptor.pipe;
Value
UsbInterruptInPipe UsbInterruptInPipe UsbInterruptInPipe UsbInterruptInPipe

An UsbInterruptInPipe object that is the pipe for the interrupt IN endpoint.
