var usbEndpointDescriptor = Windows.Devices.Usb.UsbEndpointDescriptor.parse(descriptorBulkInEp);
var usbBulkInEndpointDescriptor = usbEndpointDescriptor.asBulkInEndpointDescriptor();

Properties

EndpointNumber EndpointNumber EndpointNumber EndpointNumber

Gets the USB endpoint number of the bulk IN endpoint.

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

The endpoint number of the bulk 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.

MaxPacketSize MaxPacketSize MaxPacketSize MaxPacketSize

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

public : unsigned int MaxPacketSize { get; }public uint MaxPacketSize { get; }Public ReadOnly Property MaxPacketSize As uint// You can use this property in JavaScript.
Value
unsigned int uint uint uint

Indicates the maximum packet size of the endpoint. This value is derived from 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.

Pipe Pipe Pipe Pipe

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

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

An UsbBulkInPipe object that is the pipe for the bulk IN endpoint.

Remarks

If the alternate setting, which defines this bulk endpoint, is not currently selected, the property returns NULL.
