Not necessarily.

There are two means of keeping the names and capabilities still
available which are immediately obvious to me:

- Include the number of the real event device in the mixer's
  information, so that the application can open and query the
  appropriate /dev/input/eventXX device
- Include with each event an event number generated internally to the
  mixer (necessary if it isn't integrated into the event interface)
  and extend the ioctls to apply on a per-device basis.
