Hi,

Issue I am having is the tty's keep alternating on restart of the VM. This breaks things and is a bit tedious
Code: 
ls -l /dev/serial/by-id/*
lrwxrwxrwx    1 root     root            13 Apr 17 17:11 /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0 -> ../../ttyUSB1
lrwxrwxrwx    1 root     root            13 Apr 17 17:11 /dev/serial/by-id/usb-Silicon_Labs_CP2102N_USB_to_UART_Bridge_Controller_32ffc33f5184e91191494992d6f3a178-if00-port0 -> ../../ttyUSB0
What can I do to make the same path always point to the same tty?

Never depend on /dev/ttyUSB<N> directly, but rather on /dev/serial/by-id/.
The same for disks, there you should always use /dev/disk/by-id for stable paths.

But I do already, that is why I post. But as the ttyUSBx is the actual file, and the path "/dev/serial/by-id/..." is a link to it, it seems that link sometimes points to the wrong USB... But suppose it is not a problem with ProxMox then, it seems to be that VM that does something funny. Not a major thing, but would have been nice to stabilize this somehow. Thanks :)
