Joystick driver in ROS

edit

I am playing with the joystick driver in ROS. It works. Except that when I stop moving the joystick around, it stops sending out cmd_vels. In other words, even if the joystick is off the center position, it stops sending cmd_vels. Now this is "expected" in the case when the "autorepeat_rate" parameter is set to zero.

But I have set it to a higher number and it still is happening. I believe I have isolated it to joy_node.cpp in joytstick_drivers repo but I don't see a bug. I believe this is the source code: https://github.com/ros-drivers/joysti...

Any help will be appreciated! Here is the console output at launch:
