问题描述

你好



首先感谢你看这个。



我想用USBClassLibrary告诉我系统USB端口连接的是什么。



一切看起来都不错,(我可以根据示例编译并运行代码,加载和运行类。



我的问题是,是否有可能以某种方式获取Device_ID / SerialNumber?



(通过DEVICE ID或SerialNumber我的意思是唯一的序列号一些USB设备有)



下面的例子取自微软的USB视图,我想从USBClassLibrary获得的项目是iSerialNumber的特性。



如果您需要更多信息,请随时给我发电子邮件:

Hello

First of all thanks for looking at this.

Im thinking of using USBClassLibrary to tell me what is connected on my systems USB ports.

All looks good, (I can compile and run the code, load and run the classes as per the example.

My question is, Is it possible to get the Device_ID / SerialNumber in some way?

(By DEVICE ID or SerialNumber I mean the unique serial number some USB devices have)

The example below is taken from Microsoft’s "USB View" and the item I would like to get from USBClassLibrary is the iSerialNumber properity.

If you need any more info please feel free to email me:
