C# 클래스 LibUsbDotNet.WinUsb.WinUsbDevice

Contains members specific to Microsofts WinUSB driver.

A WinUsbDevice should be thought of as a part of, or an interface of a USB device. The WinUsbDevice class does not have members for selecting configurations and intefaces. This is done at a lower level by the winusb driver depending on which interface the WinUsbDevice belongs to.
