Adding ZWave JS to home assistant running on Synology server

Hello, I am having issues configuring zwave js and accessing the usb Zwave stick on my synology server. I watched this video and updated the usb drivers for my synology and i can now see the ‘ttyUSB0’ when logging into my server via putty but in the zwave js adon configuration I am getting this error when using this path:

device: /dev/ttyUSB0

I have also updated the firmware on the Aeotech usb stick i have.

Any help would be much appreciated
