Ok regarding Serial port in Nvidia Jetson board on Ubuntu I was looking for the FTDI kernel module but it seems to be there. Looking at the config.gz file there is :
CONFIG_USB_SERIAL_FTDI_SIO=y
However I searched for “XSENS” and fall on :
# CONFIG_USB_SERIAL_XSENS_MT is not set
So I will try to recompile the kernel with this module support. I keep you updated.
