Difference between port id's

Hi.
i am trying to setup mysensor on HASS the port id on the example show it as /dev/ttyACM0 but the id for my system is showing /dev/ttyUSB0 what is the difference and do you have to type it in the same way.
i have this setup on a Raspberry pi run Raspbian Jessie. is there a way to change the port from USB to ACM? if you need to

thanks

Usually the original Arduino boards are using /dev/ttyACMx and clones /dev/ttyUSBx.

Just adjust the “port:” entry in the configuration.yaml files that matches your port, eg. change from ACMx to USBx.

thanks for the info.
still not able to see the serial gateway (mysensor gateway), how do you know if you have a connection with HA ?
it should show on the ‘current entities’ page ?
