I have a device that I’m trying to setup some udev rules for to change the permissions of the device nodes. So the rules that I have tried they work for the device nodes in sysfs, but do not seem to work for device attributes that are exposed in debugfs (/sys/kernel/debug/…/…). Does anyone know what might be causing this?

For more information, when I run udevadm info /sys/kernel/debug/.../...:devicex that seems to actually pass but when I actually try to trigger it through sudo udevadm control --reload-rules && sudo udevadm trigger it does not seem to work.
