我正在使用 NXP LPC1788 微控制器，我正在尝试在主机上创建一个驱动程序以通过 USB 与其通信。我相信我已经设法让设备正确处理标准 USB 请求（PC 能够正确读取字符串描述符）。
不过，我在编写示例 USB 驱动程序并为设备安装它时遇到了麻烦。我正在使用 Microsoft Visual Studio 2013。我的步骤是：
创建一个 WinUSB 应用程序，它会生成一个“驱动程序”和“驱动程序包”项目。
修改生成的 INF 文件以使用我设备的 VID 和 PID。
构建项目 - 都成功构建。输出文件夹包含一个 INF 文件、一个目录文件和 WdfCoinstaller01011.dll。
通过 USB 插入微控制器，转到设备管理器→更新驱动程序软件...，浏览到包含 INF 文件的文件夹并选择它。
这会导致出现以下屏幕：
- 我选择“仍然安装此驱动程序软件”。片刻之后，它显示了这个屏幕：
我的 INF 文件如下所示：
