Have you used 'udevadm monitor' to check how your USB device is recognised? Each time it will be a different host & target and this is your problem. > How can I make a reconnect after rebooting my PC possible every time? I think that the solution is to create a udev rule which will identify your arietta interface when plugged in the PC and run the necessary script from there on.
