Since udev 247.3-7+deb11u2 /dev/serial/by-id/* symlinks are not created anymore for USB serial devices.
This is a regression from backporting udev-always-create-device-symlinks-for-USB-disks.patch It was fixed upstream by https://github.com/systemd/systemd/pull/25246 The diff doesn't apply cleanly because we don't have https://github.com/systemd/systemd-stable/commit/451ba55fecd8b494add2001b3ca3c1915c8fd655 Apply this commit and the PR fixes the issue for me.
