VLP-16 no data out over USB3.0 Ethernet adaptor

edit

Hi all,

setup:

• DELL XPS15 9550
• Ubuntu 16.04
• ROS kinetic
• Velodyne VLP-16
• USB3.0 to Ethernet Adaptor (tp-link UE300)

test ROS using .pcap works fine with the below commands

launch "lidar-data.pcap" from Velodyne using Velodyne_driver

roslaunch velodyne_pointcloud VLP16_points.launch pcap:=/path/to//lidar-data.pcap

echo the data from "lidar-data.pcap"

rostopic echo /velodyne_points

Problem: no data echo from VLP16 using the same technique from above

Steps taken for configuration:

1. set the following in IPv4 settings--IP: 192.168.1.100; Network: 255.255.255.255; Gateway: 0.0.0.0
2. sudo ifconfig enx503eaa51ef93 192.168.3.100 //enx503eaa51ef93 is the port name of the USB3.0 adaptor
3. run wireshark and identify the UDP source IP: 192.168.1.201
4. sudo route add 192.168.1.201 enx503eaa51ef93
5. Velodyne browser interface shows up fine under 192.168.1.201 (but phase=0, not sure if this is wrong)

try to view the above after configuration using

roslaunch velodyne_pointcloud VLP16_points.launch

no data echoed using

rostopic echo /velodyne_points
