Please refer to dfu-util documentation for details. The below ASCII-art presents a connection between the host and the device.

Sorry for asking some probably really dumb questions...
If I understand correctly, there is no fundamental reason why the DFU protocol would only be possible to implement over a USB link. Or am I missing something here?
Eventually it should be possible to run this protocol over Ethernet or even over a serial line?
If my assumption is correct, then what would it take to split off protocol part and make it independent of the actual driver interface?
Best regards,
Wolfgang Denk
