M4L device not initializing properly outside of editor.

I have a device which does some straightforward querying of devices in the same track. Initialization works great when triggered or re-triggered from a button in editor mode, but I can't get it to initialize properly when run outside the editor and only in Live. I tried using [live.thisdevice] to kick off the init chain, and also tried adding a 3000ms delay but it didn't help. Everything seems to work if I trigger the same init chain with the click of a button stored in presentation mode.

What are the common pitfalls with initializing M4L devices? Also, what are some ways to debug this sort of thing since print won't print to the max window when using it from Live?
