LTWheelConf - Setup Logitech DFP/G25/G27 on linux

I made a stupid mistake and was trying to test FF with the wrong event (device?)

After running

cat /proc/bus/input/devices

i saw that /dev/input/event15 is the right event handler for the attached Wheel. Running fftest on event15 works just fine.

I thought the udev rule was supposed to generate a link to the current event handler.

G27 with force feedback

Hello,

i am having difficulties to get Force Feedback running for my G27.

I am running an unmodified 3.3.6 Kernel and use the following udev rule


SUBSYSTEM!="usb", GOTO="g27_rules_end"
ACTION!="add", GOTO="g27_rules_end"

ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c29b", SYMLINK+="input/G27event"
ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c29b", MODE="0664", GROUP="agv"

ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c29b", RUN+="/usr/local/bin/ltwheelconf --wheel=G27 --nativemode --range=500"
LABEL="g27_rules_end"

After attaching the G27 i get the following output ( using dmesg)

In /dev/input/G27event is created and linked to /dev/bus/usb/001/009

When i try to thest FF with fftest, i get


root:/dev/input# fftest G27event
Force feedback test program.
HOLD FIRMLY YOUR WHEEL OR JOYSTICK TO PREVENT DAMAGES

Device G27event opened
Ioctl query: Inappropriate ioctl for device

Is anyone using FF with the G27 and a similar configuration?
Any idea why fftest failes?

Regards, and Thank you
