Sorry for this lame follow up to my own post :-/

Sorting USB traffic per endpoint and looking only at endpoints 0x0D
and 0x0E (which are obviously used for hardware register access) it
turns out that there are various unknown registers but all of these
are only used during initialisation or firmware upload. Beside these
there remain only known registers.

Despite the number of unknown registers used during firmware upload
that part is quite easy to understand, the usage pattern is very
regular and redundant.

  (data portions left out)
