检测USB连接 - C＃.NET CF 3.5 [英] Detecting USB Connection -- C# .Net CF 3.5

问题描述

我有一个是Windows Mobile 6.1设备上的应用程序（.NET Compact Framework的3.5）的运行，我想当USB连接的变化（无论是东西连接或断开连接）来检测。

I have an application (.Net Compact Framework 3.5) running on a Windows Mobile 6.1 device and I want to detect when the USB connection changes (either something connects or disconnects).

我原来使用 SystemProperty.CradlePresent 属性触发事件，但我想知道如果这仅适用于当连接该设备具有ActiveSync的？我会收到来自不具有在其上运行的ActiveSync Linux设备通过USB连接。

I was originally using the SystemProperty.CradlePresent property to trigger an event but I am wondering if this only works if the device connecting has ActiveSync? I will be receiving a connection via USB from a Linux device that does not have ActiveSync running on it.

我仍然可以使用 SystemProperty.CradlePresent 来检测来自USB的连接/断开？或者我需要寻求其他选项检测USB事件？谢谢

Can I still use SystemProperty.CradlePresent to detect the connect/disconnect from the USB? Or do I need to explore other options to detect the USB event? Thanks.

推荐答案

这也许以前我的问题可以帮助：

Perhaps this previous question of mine may help:

我如何检测USB断开事件？ （在Windows，.NET C＃应用程序）

我结束了监听和处理 WM_DEVICECHANGE 事件。他们在这里规定： http://msdn.microsoft.com /en-us/library/aa363480(VS.85).aspx

I ended up listening for and handling WM_DEVICECHANGE events. They are specified here: http://msdn.microsoft.com/en-us/library/aa363480(VS.85).aspx

不幸的是，我没有源代码的副本了，所以我的记忆它是有点朦胧。我不知道该解决方案适用于您的上下文。

Unfortunately I don't have a copy of the source code anymore so my memory on it is a bit hazy. I don't know if this solution applies in your context.
