Access /dev/ttyUSB0 from homebridge docker
I would like to use the RFlink from homebridge docker and the RFlink plugin but homebridge is not able to access the RFlink device plug in on the synology usb slot and mounted under device /dev/ttyUSB0 

**Logs:**

Homebridge log :

Unhandled rejection Error: Error: No such file or directory, cannot open /dev/ttyUSB0```

I use the docker app from diskstation, I don't know the start commande
