关于GUID的问题,求救!!

为什么我用HidD_GetHidGuid(&HidGuid)得到的是
{4D1E55B2-F16F-11CF-88CB-001111000030}?我在驱动中定义的是
Class=USB
ClassGUID={36FC9E60-C465-11CF-8056-444553540000}
是不是有什么不对啊,我用的固件是D12+51??

在注册表中是不是对？？

怎么在注册表中看啊?

看过了ClassGUID和Driver都是{36FC9E60-C465-11CF-8056-444553540000}
有什么要注意的吗?

没关系的！
INF文件的定义只是为了设置注册表项目，当然也就影响该设备在设备管理器中的位置。你的INF定义将使得设备添加到USB中去。

那按楼上大虾的意思是我HidD_GetHidGuid(&HidGuid)得到的是对的?
因为我在INF中看到的只是加到USB类中去的,而真正GUID不是那个?

没错！
INF文件用于注册表，你要用的GUID在驱动代码中定义。

哦,谢谢大虾相助,我现在能打开端口了.

是不是接下去就能调用READFILE 和 WRITEFILE了?

还有，我不大明白的地方,就是,我该什么时候去READFILE?我怎么知道我的设备什么时候有数据发送?

除了Read , Write, 还可以DeviceIoControl呀！

你的驱动中应该实现如下机制：
在读URB之前，应该给设备发一个VendorRequest，通知设备上传指定数据！并且你的读写应该加入超时机制。

非常感谢,我再研究一下,我现在已经能用WriteFile 实现简单的数据传送了.
