Realsense camera is not recognised.

[genessisperez]

Hi, I've been having an issue with the installation of the librealsense for my cameras SR300 and D400.

Until last week, the librealsense was working until I updated the firmware from the realsense camera to latest one. Then, I started having issues with the detection of the cameras.

As I was using the ROS-wrapper, I thought I perhaps cloned a wrong version of ros-realsense and decided to update it. After that, I started having issues with ros-wrapper and complaining about incompatibility. So, I thought perhaps I needed to update also the librealsense and it was a huge mistake.

So, I tried to clean up the librealsense and the ros-wrapper, and do everything from zero. I followed first the instruction from librealsense (https://github.com/IntelRealSense/librealsense/blob/development/doc/distribution_linux.md), but once I finish following all the steps and run realsense-viewer or rs-enumerate-devices, it tells me:
API version mismatch: librealsense.so was compiled with API version 2.14.0 but the application was compiled with 2.16.0! Make sure correct version of the library is installed (make install)

I failed to find any error-related in the open issues at the moment, which made me think perhaps I need to build from source. So, after removing all the SDK-packages I followed the given instructions (https://github.com/IntelRealSense/librealsense/blob/development/doc/installation.md). It builds successfully and it does not complain about any error or problem. But again, once running realsense-viewer or rs-enumerate-devices, it complains that there are no devices connected:
No device detected. Is it plugged in?

If I run $ lsusb | grep 8086 , when the camera is connected, it shows me
Bus 002 Device 009: ID 8086:0aa5 Intel Corp.

The camera are plugged using a USB 3.0, and the cameras work in different computers. Just not in mine.

The result from $ uname -r is:
4.15.0-33-generic

and I'm running on Ubuntu 16.04.1.

I don't know what to do anymore, as I've tried almost every single possible option that I've read in your Q&A and in another issues. Could someone help me?

Thanks and cheers!

Hi @genessisperez,

1. Per your USB VID/PID = 8086:0aa5, it's a SR300 device. Please run "usb-devices" to show me more info about the USB connection status.
2. What's your librs version and firmware version for SR300 and D400?
3. Find the proper ros wrapper version in https://github.com/intel-ros/realsense/releases
4. And, you can refer to below similar issue which is due to the installation and build process to cause the API mismatch.
   API version mismatch! realsense-ros#442

Hi! thanks for the answer.

So, the mismatch is fixed but still I cannot recognise the cameras (it outputs still that no cameras are connected).

I've connected now a D435 and the output is (I've attached the full output):

For the D435 the firmware version is 05.10.03.00.

Hi @genessisperez,

Per your usb device info, the uvcvideo may not loaded normally. Try to run below commands after re-connecting to SR300 or D435.
several checks:

1. "modinfo uvcvideo | grep ver"
2. dmesg
3. follow below instructions, try again to install the pre-built DKMS package, run "sudo apt-get install librealsense2-dkms", reboot your PC, then see how it works.

Hi @RealSense-Customer-Engineering

Seems like problem solved! Thanks a lot!

@RealSense-Customer-Engineering Hello, I meet the same problem, And i have tried on 4 computers by following https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md.
After the step "sudo apt-get install librealsense2-utils", the information by "modinfo uvcvideo | grep "version:" is:
version: 1.1.2.realsense-1.3.5
srcversion: 35CF6FF13E7340591034B90
And the output for "usb-devices" is :

It shows the librealsense2-dkms is the newest version 1.3.5-0ubuntu1
4\reboot
After reboot and "realsense-viewer", still no picture here.

As i tried this way in many computers, i think there maybe some steps that i missed. But only few steps to open the realsense-viewer.
The system is Ubuntu16.04, with 4.10.0-28-generic.
Any advices will help me a lot. Thanks.

@likestudy hi, please provide the details and logs for assessment -
What do you mean by no picture ? Is the camera being recognized by viewer, but you cannot start streaming ?
Which sensors did you try to activate and what were the errors you've received ?
Does the device passes enumeration correction ? What does the kernel log show when you plug-in the camera?
Can you collect and provide the realsense application console outputs and logs for

• rs-enumerate-devices -c
• rs-depth
• rs-capture

P.S: Please open a new ticket for support

[likestudy]

@ev-mp Sorry for that i did not describe my problem clearly. I open a new issue that Realsense camera can not be recognised.
Thanks for your help.
