jevois-daemon crash on ubuntu virtual machine

+1 vote
Hi, I installed JeVois on an Ubuntu Virtual Machine on OSX Mojave and when I run

jevois-daemon on the host machine using the webcam Camera, ie /dev/video0, I get this error:

INF Engine::onParamChange: Using [stdio] hardware (4-pin connector) serial port
INF Engine::onParamChange: No USB serial port used

and when I run jevois-daemon --cameradev /dev/video1 on the JeVois camera, I get this error

Can someone explain what I am missing here or what do these errors mean ?

Does the webcam work with other software?

What happens using Inventor and Jevois connected via USB?

it says waiting for JeVois smart camera, please connect JeVois to this computer.

and on the bottom left it says

Jevois Inventor 0.3.0, camera device ok, waiting for serial over usb

but it doesn't start the default module or give me the option to choose any module
