[Bug 1948538] Re: USB serial devices not available in /dev/serial/by-id/ after upgrade

[Christopher Conroy]

just to clarify, before the upgrade I had /dev/ttyACM0 and a
corresponding entry in /dev/serial/by-id/ for it.

I've verified that a fresh image of 20.04 LTS with the same device
attached does not exhibit the same issue, and the device shows up as
expected.

  I'm not sure if this is related, or a red herring.
