Hello,

I am trying to get data from xv 11 lidar, i am using UBUNTU 14.04, indigo version of ROS. I followed this tutorial:xv 11 lidar, but when ever i ran this command:

"rosrun xv_11_laser_driver neato_laser_publisher _port:=/dev/ttyUSB0 _firmware_version:=2", I am getting the following error: "[ERROR] [1460143318.307618844]: Error instantiating laser object. Are you sure you have the correct port and baud rate? Error was open: No such file or directory".

This is the output of lsusb before connecting the LIDAR:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 001 Device 004: ID 8087:0a2a Intel Corp.

Bus 001 Device 003: ID 1bcf:2b8a Sunplus Innovation Technology Inc.

Bus 001 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

This is output of lsusb after connecting the lidar: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 001 Device 004: ID 8087:0a2a Intel Corp.

Bus 001 Device 003: ID 1bcf:2b8a Sunplus Innovation Technology Inc.

Bus 001 Device 028: ID 16c0:0483 Van Ooijen Technische Informatica Teensyduino Serial

Bus 001 Device 002: ID 046d:c52b Logitech, Inc. Unifying Receiver

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I am not sure what the problem is and i am a avid LINUX user. Any help is really appreciated.

Thanks

My XV-11 shows up as: /dev/ttyACM0

One technique is to do

ls /dev/tty*

with the device unplugged, then plug it in and do it again and find out what was added.

I just did it, but i didn't find any difference. I got the same output before and after connecting the device.

may try ls /dev/* > temp.txt to get all the devices, the plug it in and do ls /dev/* > temp2.txt Then diff temp.txt temp2.txt

This is the output i got when i executed the above commands:

296a297

189:10

I have no idea what those two numbers means.

I tried do it from a different computer. Here i found /dev/ttyACM0, But i am still getting the same error. Any insight into the problem?

Try this unplug it and plugging it back in, then do a dmesg, at the bottom it should show what device was added. Look for something like this cdc_acm 1-1.5:1.0: ttyACM0: USB ACM device if it nothing shows up it might be problem with your hardware. Does the laser spin while plugged in?

on the 296a297, diff is reporting that one line was added between the two temp files on line 297. Mine reports `130a131

/dev/ttyACM0`
