Revision 583, 4.7 kB (checked in by ppalmers, 16 years ago)

- Clean up the FFADODevice constructor to remove the nodeid that

can be retrieved from the configrom.

- Implement new method of creating devices: a device is supposed

to implement the createDevice static method that should return
an instance of itself or a subclass of itself. This should ease
support for manufacturer specific customizations since we don't
have to put them into the device manager class.
