no realsense device found: realsense D415 camera

[IYada]

Hi,

I recently brought a realsense D415 camera. I am using ubuntu 14.04 and installed ros-wrapper and realsense SDK from https://github.com/intel-ros/realsense/releases Releases · intel-ros/realsense · GitHub. All the installation works ok but when I launch the rs_camera.launch file I get error

[ERROR] [1523460413.786180365]: No RealSense devices were found! Terminating RealSense Node...

There is no light in the camera when I plug it in with the usb3.0 cable that came with the camera. the output of lsusb is:

the kernel version

Please let me know what I can do to solve this problem.

Thanks,

for:"EDIT: Oh, so you are failing at the Xenial instruction, so can't get that far?"

I hope I am not doing something stupid. the steps you said are listed under heading "make ubuntu up to date" I could do them. after that I fail at patch kernel module step. Even after failing I go ahead and complete all the steps.

[IYada]

yes, exactly before this step.

The instructions are not as clear as they could be, so it's understandable if you missed something. I read them often and still check them several times every time I quote them.

Let's do a recap of the process.

1. Update Ubuntu distribution, including getting the latest stable kernel

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

As you have kernel 4.4, you should not need to use the longer instruction for 'stock Ubuntu 14 LTS systems', as it is intended for installations with kernels earlier than 4.4.
