try this:
...
deviceInterface = new QDBusInterface("org.freedesktop.Gypsy", "/default", 
"org.freedesktop.Gypsy.Device", QDBusConnection::systemBus(),this);

Qt doesn't need the full path for the node again. 


Here you find some very useful QtDBus examples:
http://techbase.kde.org/Development/Tutorials#D-Bus

Not sure if you know about "qdbusviewer". It comes with your Qt4 installation 
and helps you a lot debugging and understanding DBus.

Hope this helps.
