[solved] Serial port broken after last update, uucp invalid user now

After the last update my serial ports /dev/ttyACM* are now all owned by the root user.
When I try to chown them to uucp it says its an invalid group.

Any idea why this change was made?
Is this a bug or intentional change?
How can I change this back?

Okay I see my problem…
different commands are pointing to different locations.

[s@s-pc ~]$ ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Dec  3 12:31 usb-Pulse-Eight_CEC_Adapter_v8-if00 -> ../../ttyACM0
