Astra pro,little topic

Hi guys,
I have a question about ORBBEC Astra pro, after running the command:
roslaunch astra_camera astra_pro.launch.
rostopic list displays only:

~$ rostopic list
/camera/color/camera_info
/camera/color/image_raw
/camera/depth/camera_info
/camera/depth/image_raw
/camera/depth/points
/camera/depth_registered/points
/camera/extrinsic/depth_to_color
/camera/ir/camera_info
/camera/ir/image_raw
/camera/reset_device
/rosout
/rosout_agg
/tf
/tf_static

Only 5 topics are available in rviz. What could be the problem?
Thanks for the answer.
