It sounds like you want different sets of properties for each instance 
of the class, depending on the capabilities of the device it represents.

GObject property definitions are class wide, so if you add or remove a 
property after class creation, it is going to affect all instances which 
might not be what you want.

If you really want a different set of properties per instance, you'd 
need a new class per instance.  In that case, you could just add the 
required properties when you create that class.  Of course, this 
probably uses more memory than you'd prefer.
