A 16500 has two internal HP-HIL devices the knob and the IR touch
screen sensor that are likely configured before external devices.

Interestigly enough does the HIL docs claim that autoconfigure
always starts with ACF1 (0x09) and so it does on my 340, but here
it starts wth ACF3 (0x11). The way autoconfigure works is that the
host sends, say 0x09 and the first unit takes the lower three bits
as its address, increments and passes on.
After the host has gotten the incremented ACF back, it should
issue an IDD for every address and then an EPT (enterpassthrough)
On my 340 it is the other ay around and it always seem to assume
address 4, no matter what.
