Thanks for the help. I cleared the eeprom again just to confirm that it isn't causing the problem and the connection still is not working.
Here's the serial output from the gateway:

I've added it all as I'm not sure what is relevant:grin:
Here is the mysensor config in the configuration.yaml file:
mysensors:
gateways:
- device: '/dev/ttyUSB0'
baud_rate: 115200
optimistic: false
persistence: true
retain: true
version: '2.3'
