udev problem with PEARL display at dockstar / lcd4linux (no replies)

Dear all,

context: PEARL Display at Dockstar on Debian Wheezy

I have problems with udev while connecting the PEARL display to a dockstar. The problem is not lcd4linux, that works and the display is immediately in hack-mode after connecting via usb. So a "/usr/local/bin/lcd4linux" on the commandline works out of the box.

The 70-dpf.rules in /etc/udev/rules.d that was written should not be a problem too, because the same config works on another computer (notebook, same OS, same display, same config of lcd4linux):

SUBSYSTEM=="usb", ACTION=="add", ENV{ID_MODEL_ID}=="0102", ENV{ID_VENDOR_ID}=="1908", RUN+="/usr/local/bin/lcd4linux"
SUBSYSTEM=="usb", ACTION=="remove", ENV{ID_MODEL_ID}=="0102", ENV{ID_VENDOR_ID}=="1908", RUN+="/usr/bin/killall lcd4linux"

Now for lsusb:

lsusb -v

That seems to be ok too. Now for udev (debug mode /var/log/syslog):

It seems the written 70-..rules was not used.

What's wrong and how to fix it?
Any package missing?

here the error while disconnecting the display:
