I run a Digi003 and an 11-Rack. I only want the 003 as my main interface, so I make sure the 11-R is turned off when I boot up and start Protools. That way it is always the interface that PT sees.

I then turn on the 11-R after I am booted up & PT is started, and I can use it as a standalone on a given channel.

Whatever you want to use for your interface - make sure it is connected and turned on when you boot up and when you start PT. FYI, I have found that if both are turned on it will not see the 003, and will load the 11-R as the default.
