Can't create a mathcing udev-rule....

[Daniel Spannbauer]

Hello,

I try to create a udev-rule for the USB-Devices produced by our company.
Espacially one device drives me crazy.
This is a board connects via USB, the kernel creates a tty
(/dev/ttyUSB?). Other USB-Devices can be connected to this "baseboard".

To create a unique Devicenode to that Baseboard I have to create a
UDEV-Rule. For the other devices connected to that baseboard a rule
already exists.

Here is the ruleset for our devices:

=======================# rule for io-interfaces
SUBSYSTEMS= "usb", KERNEL="ttyUSB[0-9]*", ATTR{idVendor}="1dfb",
RUN+="/usr/uti/udevscript usbmodul %k $env{ID_SERIAL_SHORT}"
# additional rule for io-interfaces to read with control485
SUBSYSTEMS="tty", KERNEL="ttyUSB[0-9]*", ACTION="add",
RUN+="/usr/uti/udevscript-485 usbmodul %k $env{ID_SERIAL_SHORT}"
SUBSYSTEMS="tty", KERNEL="ttyUSB[0-9]*", ACTION="remove",
RUN+="/usr/uti/marco-udevscript-485 usbmodul_remove %k"
# USBSTICK
SUBSYSTEMS= "usb", KERNEL="sd[a-z]1", RUN+="/usr/uti/marco-udevscript
usbstick %k"
SUBSYSTEMS= "usb", KERNEL="sd[a-z]", RUN+="/usr/uti/marco-udevscript
usbstick_device %k"
# PCAN
SUBSYSTEMS= "usb", ATTR{idVendor}="0c72", ATTR{idProduct}="000c",
RUN+="/usr/uti/udevscript pcan"
# 2a-Board
SUBSYSTEMS="usb", KERNEL="ttyUSB[0-9]*", ATTRS{idVendor}="1dfb",
ATTRS{idProduct}="0007", SYMLINK+="/dev/2a/%k"
========================

Here is a "/sbin/udevadm info --query=all --attribute-walk
--name=/dev/ttyUSB0" for that device (it is reachable over /dev/ttyUSB0):

I disconnect and connect that device....but nothing is created under
/dev/2a.

Any hints about this ruleset?

Regards

Daniel
