No, it's not working either.... when I insert or remove my USB
device the 'WMDiskChange' function is call several times but at
each call I see in the debuger that Message.WParam = 7, when I 
insert, or when I remove the USB connector of the device. 

Any idea why? can it be a problem in the device itself?

Here is my last code - 


  void __fastcall WMDiskChange( TMessage &Message );

  BEGIN_MESSAGE_MAP
      MESSAGE_HANDLER( WM_DEVICECHANGE, TMessage, WMDiskChange )
  END_MESSAGE_MAP( TControl )


void __fastcall TForm1::WMDiskChange( TMessage &Message )
{
  int Value;

  Value = Message.WParam;  
  Value = Value;            // I set my breakpoint here 
}
