I think that the problem is not network related, but USB rules related. |

Have you used 'udevadm monitor' to check how your USB device is recognised? |
| 53 |
Each time it will be a different host & target and this is your problem. |

arietta interface when plugged in the PC and run the necessary script from |
| 60 |
there on. |

Have a look here for persistent device naming: |
