Support of the digi hardware will, as I understand it, require a lot more than just configuration information. Since the digi hardware is based on a non-standard proprietory platform it will require the writing of a driver for the digi hardware. AFAIK digi won't cooperate with our project so you'll have to acquire the knowledge through protocol analysis. To do this most efficiently you'll need a PCILynx card in a Linux PC connected on the bus between your 003 and a computer running an OS supported by digidesign. Assuming you aren't restricted by any EULAs you have agreed to by using your 003, you will then need to analyse the protocol to work out how to drive the device and then use this knowledge to write a FFADO driver for the 003.

It will be a lot of work. Check out my numerous postings on ffado-devel on how to go about this (messages will most likely have "MOTU" in them since that is the driver I was working on). Feel free to contact me via the list if you want further information.
