Udev doesn't create symlink


Hy!

I would like to make a symlink and run a bash-script if a user attaches a new pendrive in a specific port.

Here is my udev rule file:

ACTION=="add", SUBSYSTEM=="usb", KERNEL=="1-1.4:1.0", DRIVER=="usb-storage", SYMLINK+="/dev/ext0"
ACTION=="add", SUBSYSTEM=="usb", KERNEL=="1-1.4:1.0", DRIVER=="usb-storage", RUN+="/mybin/usbhandler/pendrivehandler.sh"

My shell-script runs without any problem, but the symlink doesn't created. Have you any idea, what is my mistake?
(I tried them to put in one line, but it didn't work either.)

Thank you for your help. Have a nice day!

Ps.: I am using the newest Raspbian.

Just from a quick look at an existing rules file: You have to leave out the "/dev/" from the path:

Code:
SYMLINK+="ext0"
Also: What udev version, and is there anything in any log file after the script has run?

Hy Cepheus11,
I removed the "/dev/" part, but it's still wrong.
The output of "udevadm --version" command is 175.

I run the "udevadm --debug monitor" command and reconnect my pendrive. My output is:

I can't see any debug or warning message, I also checked the syslog, but nothing.

Have a nice day!
