I am trying to give my sensor device a static name. I opened a file called 99-usb-serial.rules in /etc/udev/rules.d and wrote the following rule:

KERNEL=="ttyACM0",KERNELS=="1-1",SUBSYSTEM=="tty",SUBSYSTEMS=="usb",ATTRS{idVendor}=="108c", ATTRS{idProduct}=="017b", SYMLINK+="/dev/mydevice"

This does not create any symlink in /dev.
To check whether my command is correct or not,

Command:

udevadm -info --name/dev/ttyACM0 --atribute-walk

output:

Udevadm info starts with the device specified by the devpath and then

walks up the chain of parent devices. It prints for every device

found, all possible attributes in the udev rules key format.

A rule to match, can be composed by the attributes of the device

and the attributes from one single parent device.

To debug the problem, I used udevadam test
Command:

sudo control --reload-rules --log-priority=debug && udevadm trigger

sudo udevadm test  $(udevadm info -q path -n /dev/ttyACM0)

output:

This program is for debugging only, it does not run any program

specified by a RUN key. It may show incorrect results, because

some values may be different, or not available at a simulation run.

Problem seems to be here I guess:

But I don't know how to fix this. The other answers does not seems to be helpfull.
