RuntimeError: No device connected

[Benz-Tracxpoint]

Required Info
Camera Model	D400
Firmware Version
Operating System & Version	Ubuntu 16.04
Kernel Version (Linux Only)
SDK Version	2

Following Compilation of the SDK with its python Wrapper I try to run the following code:

    pipeline = rs.pipeline()
    config = rs.config()
    config.enable_stream(rs.stream.depth, 640, 480, rs.format.z16, 30)
    config.enable_stream(rs.stream.color, 640, 480, rs.format.bgr8, 30)
    cfg = pipeline.start(config)

but the following error keeps showing even-though the device is connected:

  File "rs_tools.py", line 85, in <module>
    record_aligned_rgbd_to_disk_dirs(baseDir,True,True)
  File "rs_tools.py", line 20, in record_aligned_rgbd_to_disk_dirs
    cfg = pipeline.start(config)
RuntimeError: No device connected

As mentioned above, the Device is connected, and the same code worked for us on a windows operation system

any ideas what are we missing?

Hi @Benz-Tracxpoint
Please see the troubleshooting WIKI. Does the system recognise the device (shows it under lsusb | grep 8086)?
In addition, please post the dmesg logs when connecting the device.

Hן Sergey,

Bus 002 Device 005: ID 8086:0b07 Intel Corp.

Hi @Benz-Tracxpoint ,
Did you follow the linux installation chapter to set the required patches and permissions?
If so - please run 'rs-enumerate-devices' and post here.

Hi,
I was finally able to get it work after following this tutorial as well: https://software.intel.com/sites/products/realsense/sdk/getting_started.html#Setting_Up_Your_C_Development

When I ran into this issue, a sudo apt update after the step of adding the librealsense server to the repo list did the trick.
