I’ve got a USB device which exposes 2 CDC-ACM endpoints and one USB-DFU endpoint. I want to ensure all endpoints can be accessed by the logged-in user, and additionally that the CDC-ACM endpoints’ TTY devices show up as /dev/ttyCUST# for some number #. I don’t care if they still show up as /dev/ttyACM#, just as long as they also end up as /dev/ttyCUST#.
I’ve got the following UDEV rules in my configuration:
services.udev.extraRules = ''
SUBSYSTEM=="tty", ATTR{idVendor}=="36dc", ATTR{idProduct}=="0005", MODE:="0660", TAG+="uaccess", SYMLINK+="ttyCUST%n"

Since the wakeup calls show I believe the rule is being run.
The configuration does add the rule to /etc/udev/rules.d/99-local.rules as expected, but no /dev/ttyCUST# symlink is created. What do I need to get the symlink to work?
Seems like 60-serial.rules gets applied, but 99-local.rules doesn’t.
