wince设备枚举错误

[devilgavin]

在Wince下，调试驱动时发现这样的错误，造成串口驱动没有加载上：
DEVICE!RegReadActivationValues RegQueryValueEx(Drivers\BuiltIn\Serial\DllName) returned 2
DEVICE!I_ActivateDeviceEx: can't find all required activation values in 'Drivers\BuiltIn\Serial'

有遇到过这样的问题么，请给指导下。

从代码上看不到有什么问题，其它的驱动也是通过这种方法加载的。只在加载serial时出错。

我贴出的代码是从wince7中private路径 下复制出来的，应该没问题啊。

楼主的注册表配错了

请问，具体哪个参数错了？

[猫xiaowai]

看看注册表有没有配置正确。

没有修注册表，这个注册表在CE6下运行正常，在CE7下，就不正常。

麻煩 LZ 將 %_FLATRELEASEDIR%\reginit.ini 中, [HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial] 也貼出來, 應該就可以看出端倪了

这块是device.dll调用busnum.dll
busnum.dll在调用RegQueryValueEx查询Serial驱动的dll名称时没查到
RegQueryValueEx(Drivers\BuiltIn\Serial\DllName)
记得驱动里面都是Dll键值是记录流驱动dll名称的
会不会是wince7去读的键是DllName而不是Dll
把Serial注册表的Dll修改为DllName试试呢？

又在设备上做了测试，串口驱动已经加载了，uart1也能正常工作，但在系统初始化时，总是报这个错误。没有找到具体原因。
