Welcome to the osspd list :)
I am using a very similar setup (linux 3.13.7, Debian amd64, libfuse
2.9.2), so this should really be working. But as you discovered, the
error reporting of osspd is... improvable.

Some questions to start with:
* Did you run this as root?
* Did you load the cuse module beforehand, and check that it
  loaded successfully ("lsmod | grep cuse")?
* Do the device files already exist? The OSS module must be unloaded,
  of course, and no other instance of osspd must be running.
  I am getting exactly the errors you are describing when running
  osspd here again, while it is already running in the background.
  ("ls /dev/{*dsp,mixer} -lah", "pidof osspd", "lsmod | grep oss")

If the answer to the above is yes/yes/no, please run osspd with strace,
that should give a better indication what's failing:

  strace osspd -f -v 2> osspd-strace

Kind regards
Ralf
