I'm trying to install this package and after invoking the softkinetic_cameras.launch file get the following screen dump with an exception

I can't seem to find any posts with this particular exception that can help me figure out what i'm doing wrong ... can anyone help me?

Hi @kstanhouse, the softkinetic_cameras.launch launcher assumes you have two softkinetic cameras, while it seems you have only one. The first one probably succeed connecting as device '0', but the second one fails to connect as device '1'. You can verify if this is the problem by starting another launch file, for example softkinetic_camera_ds311_demo.launch. Please tell us if that one works.
