Could not open symlink to port /dev/ttyACM*

edit

Hi,

tl;dr: I am unable to use my symlink to run rosserial since I would always get a message that there is no such file or directory with the symlink I created.

I've created a symlink to my arduino device using the following udev rules:

KERNEL=="ttyACM[0-9]", MODE="0666"
ACTION=="add", SUBSYSTEMS=="usb", ATTRS{serial}=="8563332343035180E191", ATTRS{idProduct}=="0043", ATTRS{idVendor}=="2341", ATTRS{manufacturer}=="Arduino (www.arduino.cc)", SYMLINK+="/tty-arduino-uno"

and I can see that the symbolic link has been created since I would get this output:

$ ls -la /dev/tty-arduino-uno 
lrwxrwxrwx 1 root root 10 Jun 29 14:52 /dev/tty-arduino-uno -> ../ttyACM1

Now I wanted to run rosserial_python with this symlink but I would always get this error message when I run rosrun rosserial_python serial_node.py _port:=/dev/tty-arduino-uno:

[ERROR] [1530309034.478989]: Error opening serial: [Errno 2] could not open port /dev/tty-arduino-uno: [Errno 2] No such file or directory: '/dev/tty-arduino-uno'

However, rosserial_python still works when I do

rosrun rosserial_python serial_node.py _port:=/dev/ttyACM1

I get the following when I run udevadm info -a -n /dev/ttyACM1:
