2019-08-09 17:03:39 -0500 marked best answer Unable to connect more than one USB 3.0 Basler Cameras

I am trying to connect 2 Basler Cameras by setting respective device ids using pylon_camera node. But it does not pick the device id correctly. Without setting the device id it works.

I have set the permission for USB devices as mention here ( https://www.baslerweb.com/fp-15101246... ) by executing ./setup-usb.sh . But when I specify the device id (e.g, 2676:ba02:2:2:8) in the config file it does not detect the corresponding device. This is the error it is throwing

[ INFO] [1531469242.730556970]: Trying to open the following camera: 2676:ba02:2:2:8
 [ERROR] [1531469242.994999730]: Couldn't find the camera that matches the given DeviceUserID: 2676:ba02:2:2:8! Either the ID is wrong or the cam is not yet connected

Maybe device id was set incorrectly. Anybody who can comment on this much appreciated.

This way works for me, add launch-prefix="valgrind --tool=callgrind --callgrind-out-file=/home/project/test.log" in you

Once the user id is assigned to the camera is it persistent and does not need to be rewritten on each camera power up?
