Two additional comments: 1) The firmware file is likely at the Windows driver for this device (probably using a different format). It should be possible to get it from there. 2) Another possibility would be to add a way to tell the si2168 driver to not try to load a firmware, using the original one. That would require adding a field at si2168_config to allow signalizing to it that it should not try to load a firmware file, and add a quirk at the af9035 that would set such flag for Logilink VG0022A. Option (1) is the best one. Thanks, Mauro
