Problems with opening mono (rgb) camera : NxLib exeption

[Beginner045]

Hi everyone,

I am a beginner to be working with cameras and perception. I am trying to use an Ensenso N35 (stereo camera) with UI5240CP-C-HQ-R2( rgb camera). I tried to use this driver by running the viewer.launch file with parameters for the cameras. This successfully connects to and opens the ensenso stereo camera, however throws an nxLib exemption while opening the rgb camera and aborts.

`Done checking log file disk usage. Usage is <1GB.

started roslaunch server http://MRK01-U:45343/

I tried to troubleshoot the connection to rgb camera using the ueyecameramanager :
Status of device 1002: The camera is configured correctly and can be opened.

Also tried to restart the camera daemon using the following commands.
sudo /etc/init.d/ueyeethdrc force-stop Killing ueyeethd... Done.
sudo /etc/init.d/ueyeethdrc start Starting ueyeethd... IDS ueyeethd 4.90.13.0 64bit build Sep 28 2017 08:45:25 ( cmdl cap hll scq ) ueyeethd is running.
There seems to be no issue here.
Could somebody please help me in this regard ?
