In the launch file I have only added the serial number as a parameter and it seems to start launching the correct things... to make sure I've installed everything correctly I even tried the launch file for the Phidgets Spatial IMUs and these launched without any problems.
I am using ros noetic on a Ubuntu 20.04 based distribution and a Phidget HighSpeed Encoder 1057-2.
Am I overlooking something in the launch file?
