Hi,
When the CX3 is connected to Ubuntu 18.04 OS which is using kernel 4.16.2-041602-generic means its getting detected as two /dev/video devices.
kernel 4.13.0-26-generic one /dev/video device as expected
kernel 4.16.2-041602-generic two /dev/video devices !!!
We have loaded the cx3_examples project "cycx3_uvc_ov5640". Is anyone seeing similar kind of issue ?
Thanks & Regards,
Shanthakumar

You can close this case. Updating the kernel resolves the issue.

How do you confirm that the two videos devices shown for CX3 UVC device? Please get the VID and PID of the each video device to confirm this.
Please check the devices connected using lsusb command. It must be showning only one CX3 device in both the kernels.

Hi Srdr,
1. First i have used "lsusb" command to list the USB devices. Here i found only one number of usb device with our VID & PID(2560, D051) got detected. Please find the screenshot below.,
Before connecting the camera :
After connecting the camera :
2. I have checked the "ls" command on "/dev" directory to display for the video nodes.
Before connecting the camera :
After connecting the camera :
3. I have also used the "v4l2-Ctl" tool to display all the information belongs to that specific video nodes.

Video Node 1 :
Please let me know if you need any other input.
Thanks & Regards,

Hi Srdr,
As far as i have tested, the functionality doesn't seems to be not affected. But we are getting 2 video nodes, accessing the other video node results in application crash.
Thanks & Regards,

Shantha Kumar,
Can you please confirm by connecting another Camera (other than CX3) to kernel 4.16.2-041602-generic machine and check?
This will help us in understanding whether this is happening with kernel 4.16.2-041602-generic or anything need to be done in CX3.
