Need to setup a catkin workspace and build before use.
Install the udev rules for the Razer Hydra by running the configure script in the razer_hydra directory:
roscd razer_hydra ./configure_udev_rules
Source the setup file in devel folder before running, and when you try to display/echo the controller data in a new terminal.
For publishing the raw controller data, launch: roslaunch razor_hydra hydra.launch
For publishing processed data, launch after publishing the raw controller data: roslaunch touch_tmr hydra_sub_pub.launch
