Hi, when I connect OR disconnect the USB connector I reach the 
breakpoint in function "OnDeviceChange", but the parameters 
of 'm' are stay the same (it is not right), why?

Thanks.


public:		// User declarations
 __fastcall TUSBApp_form(TComponent* Owner);
        // Overriding a message handle

 //Messages::TMessage message;
 void OnDeviceChange(Messages::TMessage );

 BEGIN_MESSAGE_MAP
   MESSAGE_HANDLER(WM_DEVICECHANGE , Messages::TMessage , OnDeviceChange)
 END_MESSAGE_MAP(TComponent)

//---------------------------------------------------------------

void TUSBApp_form::OnDeviceChange(Messages::TMessage m)
{
 //USBC->OnDeviceChange(m);

 return;  // Breakpoint Here 
}
