Retrieving info from DBUS at application startup

[Frank Aune]

Hello,

Detecting Hotpluggable hardware using DBUS works great, but usually 
peripherals are already connected when launching the application. How can I 
(preferably using DBUS) detect which USB printers for example are connected 
to the system at application launch without engaging in some insane probing 
activity?

Thanks,
