I am using Ubuntu 12.04 64bit LTS and am trying to use a Logitech G27 Steering Wheel and Pedals. Everything but the steering feedback is working fine.
I can test the feedback with
(note the line "Axes query" is empty)
$ fftest /dev/input/event11 Force feedback test program. HOLD FIRMLY YOUR WHEEL OR JOYSTICK TO PREVENT DAMAGES Device /dev/input/event11 opened Axes query: Effects: Constant Number of simultaneous effects: 16 Upload effects: Invalid argument Upload effects: Invalid argument Upload effects: Invalid argument Upload effects: Invalid argument Upload effects: Invalid argument Enter effect number, -1 to exit 1 Now Playing: Constant Force
but the feedback is very weak and it does not work with
ffcfstress or my target application.
$ ffcfstress -d /dev/input/event11 -o ERROR: device (or driver) has no force feedback support [ffcfstress.c:166] $
I hope you can help me with this problem. Thanks.
I tried with Ubuntu 14.04 and I can use ffcfstress to use force feedback. Unfortunately we'd like to stay with Ubuntu 12.04 since all this is running on a cluster machine with many people working on it. It also works on OSX with SuperTuxKart (I know, a professional way to try it out.)
