A system has two USB printers. The administrator needs to create a udev rule that assigns a persistent symlink /dev/printer1 to the printer with serial number ABC123, and /dev/printer2 to the printer with serial number XYZ789. The administrator writes the rules, but after reloading, both printers get the same symlink. What is the most likely cause?

The rules use ATTR instead of ATTRS, so the serial number is not matched correctly.

The rules are in the wrong file, so they are not being read.

The rules are missing the SUBSYSTEM=="usb" match.

The rules use SYMLINK+= instead of SYMLINK=.
