推荐答案

因为您没有说任何一种方式...

如果是USB设备，则可以截取适当的Windows消息，通知系统已插入新设备.这是我使用google找到的CodeProject文章.

枚举和自动检测USB驱动器 [

Since you didn''t say one way or the other...

If it''s a USB device, you can simply intercept the approprioate windows message that notifies the system that a new device is plugged in. Here''s a CodeProject article that I found using google.
