The Maestro 3 is a different beast than the Maestro 2 it seems... FreeBSD
has a separate maestro3 driver in their source tree. Looks like you'll
have to write your own driver for the thing...

Looking at their maestro3.c, there are links to some resources that would
most likely be helpful:

  http://www.zabbo.net/maestro3
  http://virgo.caltech.edu/~dmoore/maestro3.pdf.gz

and of course, you could always look at FreeBSD's
sys/dev/sound/pci/maestro3.c for help as well.

Hope this helps,
