我正在使用 NXP LPC1788 微控制器，并尝试在主机上创建一个驱动程序以通过 USB 与其进行通信。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，生成“驱动程序”和“驱动程序包”项目。
修改生成的 INF 文件以使用我的设备的 VID 和 PID。
构建项目 - 均构建成功。输出文件夹包含 INF 文件、目录文件和 WdfCoinstaller01011.dll。
通过 USB 插入微控制器，然后装置经理 → 更新驱动软件...，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”。过了一会儿，出现这样的画面：
我的INF文件如下：
