When a usb device being plugged in or off a port, the system can detect the message. Some solution is that using the "InstallWinMsgCallback ()" function to process the message, this way need that there must be a special cvi panel to receive the message. Due to my application is a Windows service, so I can not make a panel. I'd like to know is there any way to capture the message using the "RegisterWinMsgCallback()" function? If it will, how to do this? Thanks.
