AFAIK I'm the only FFADO developer equipped to investigate these protocols
(please correct me if I've missed anyone) and unfortunately I don't have
access to an 896HD. This makes the deduction of the protocol rather awkward
at best. To do useful tests yourself you need at the very least a
PCILynx-based firewire card, the nosy software, a knowledge of the firewire
protocol and a willingness to hack nosy to get the information you need.
Does this sound like the kind of thing you could do?
For the sniffing, should I run the MOTU windows software (I haven't used this yet), and sniff on the same PC? Or do I need to stick another PC (with the PCILynx card) between the windows PC and the MOTU? What s/w do you use to do the sniffing? I've got XP installed on my windows PC, and I have another spare desktop that I can put whatever on (currently has FC4).
What's a good starting point for reading about the 1394 protocol? I found a 137 page "overview" of all the specifications on this page:
I've got some reading ahead...
