I have a raspberrypi 3. If I put a usb serial rfxcom device in the USB port I get a ttyusb0 serial device with ftdi drivers, but I have another USB stick with serial interface easywave which does nothing, on a windows computer it is a serial device. How can I let my pi 3 see it as a serial device?
i am running

i know the usb stick Easywave from Eldat should use the
but the descripters for the usb easywave device aint formulated on the silicon labs driver
i added them in a pull request for the linux distribution , it is a bridge to far for me to update the driver itself in my pi 3 ,

a workaround is mentioned on stackoverflow
