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
