在Windows 7下，函数SetupDiEnumDeviceInterfaces失败，并显示1008错误代码

本文介绍了在Windows 7下，函数SetupDiEnumDeviceInterfaces失败，并显示1008错误代码的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

您好，

我们正在将HID设备支持应用程序从Windows XP移植到Windows7.

问题是该应用程序在Windows 7下找不到该设备，尽管在Windows XP下可以正常运行.函数SetupDiEnumDeviceInterfaces失败，错误代码为1008(尝试引用不存在的令牌.").操作系统正确枚举了我们的设备，并且在应用程序外部(相对于操作系统)正常运行.只是我们的应用程序不能(在Win 7下)使用其接口之一(有3个)来设置通信.

任何建议将不胜感激.


这里代码是:

 

Hello,

We are porting our HID device support application from Windows XP to Windows 7.

The problem is that the application can not find the device under windows 7, though it worked OK under Windows XP. The function SetupDiEnumDeviceInterfaces fails and the error code is 1008 ("An attempt was made to reference a token that does not exist."). The OS correctly enumerates our device and it functions correctly outside our application (vs. OS). Just our application can not (under Win 7) setup communication with one of its interfaces (there are 3).

Any suggestion will be appreciated.
