Errors when using package

Error: Could not open the space navigator device. Did you remember to run spacenavd (as root)?

Example:

• blaise@hya: /opt/ros/cturtle/stacks/joystick_drivers/spacenav_node $ ./spacenav_node 
  connect failed: No such file or directory
  [ERROR] [1288904194.289257379]: Could not open the space navigator device.  Did you remember to run spacenavd (as root)?
  [ WARN] [1288904194.289311637]: Publisher on '/spacenav/joy' destroyed immediately after creation.  Did you forget to store the handle?

Solution:

• Did you run spacenavd?

  sudo bash
  rosrun spacenav spacenavd

• Did you run spacenavd via sudo? In some conditions, running

  sudo rosrun spacenav spacenavd

  does not work. Use the invocation above if you run into trouble.
