The "Device Firmware Upgrade Specification" describes a vendor- and
device-independent way of downloading a firmware image to a USB
device. Older USB devices from Midiman (MidiSport interfaces,
KeyStation keyboards) required a device-specific firmware loader, but
when a device implements the DFU specification (such as the Sonica or
the Ozone), it is possible to use one loader for all these devices, so
user's don't have to wait until somebody manages to write a loader for
their device. (Of course, now you have to wait for somebody to write
the DFU loader, but that's only once. :)
