Title:
  After suspend, ttyusb0 is moved to ttyusb1

Status in systemd package in Ubuntu:
  Invalid

Bug description:
  I have an old Core2 Duo running Ubuntu 20.04.
  As it was sluggish with gnome, I installed the xfce environment (only xfce, not xubuntu)

  Yesterday, I was using minicom then I suspended my laptop.
  When I restarted minicom reported it could not open ttyusb0

  After a few checks, I noticed that my usb to serial adapter was now
  ttyusb1. I did not try to replicate.

  This is quite annoying if you intend to rely a lot on suspend.

  This behavior used to be in Windows in the past, but I believe they
  use the UUID to always assign the same port to a USB device, as under
  Windows, wherever I plug my US?B device, it always identifies as the
  same "COM" port (used not to be the case before).
