First time after starting PC I can launch camera by:> roslaunch usb_cam usb_cam-test.launch
However after closing it, using ctrl+c in the terminal and running again I get following error:
> [ERROR] [1548665838.684033928]:> VIDIOC_S_FMT error 5, Input/output> error [usb_cam-1] process has died> [pid 7194, exit code 1, cmd> /opt/ros/kinetic/lib/usb_cam/usb_cam_node> __name:=usb_cam __log:=/home/nuvo/.ros/log/a60e58e0-22c3-11e9-8944-f81a670f7983/usb_cam-1.log].> log file:> /home/nuvo/.ros/log/a60e58e0-22c3-11e9-8944-f81a670f7983/usb_cam-1*.log
