I have See3CAM_CU30 UVC camera. My aim is to drive that camera with ROS Melodic.

Before plugging in the camera to the USB, output of command below is :

"No such file or directory"

ls /dev/video*

After plugging in the camera to the USB, output of command above is:

 "/dev/video0  /dev/video1"

Then, I check the USB attributes of the camera using this command, and required output is:

udevadm info --name=/dev/video1 --attribute-walk

    ATTRS{idProduct}=="c130"
    ATTRS{idVendor}=="2560"
    ATTRS{manufacturer}=="e-con systems"
    ATTRS{product}=="See3CAM_CU30"
    ATTRS{serial}=="3B1B0205"

Then, I create /etc/udev/rules.d/99-uvc.rules with these parameters:

SUBSYSTEMS=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="2560", ATTRS{idProduct}=="c130", MODE="0666"

After that:

sudo udevadm control --reload-rules

Also output of of the command "v4l2-ctl --list-formats-ext -d /dev/video0" is:

Output of the command "v4l2-ctl --list-formats-ext -d /dev/video1" is only:

 ioctl: VIDIOC_ENUM_FMT

And my launch file:

<launch>
  <group ns="camera">
    <node pkg="libuvc_camera" type="camera_node" name="mycam">
      <param name="vendor" value="0x2560"/>
      <param name="product" value="0xc130"/>
      <param name="serial" value="3B1B0205"/>
      <param name="index" value="1"/>
      <param name="width" value="1920"/>
      <param name="height" value="1080"/>
      <param name="frame_rate" value="15"/>
      <param name="video_mode" value="uncompressed"/>
    </node>
  </group>
</launch>

I get that error:

[ERROR] [1608057844.165794371]: Unable to find device at index ...
