Any hint is always precious:

What do you mean for report ID? The message to be sent to
device?
But before sending report, I can't find the item-address to
send to:

WARNING: hid_find_object(): can't find requested item
0xff000001.0x00010046.0x000a0001 of USB device
002/002-1b67-000a-00-00[0].

I tryed almost every combination of what test_libhid tells
about the device:

I will add this and retry, but I'm working abroad and I can
access my mail only at the office, so I can tell tomorrow
about this...
thanks a lot!
