Ok, thanks a lot for this info !

Hi MadCatX,
I'm not at home currently, so I can't give you the exact kernel version I have. Nevertheless, one data, I use Kubuntu 14.04 LTS, up to date.
I will check my kernel version as soon as I will be back home and also take a look about js device instead of event one.
Anyway, as I don't know how is working the driver, I don't understand why I can't edit the /sys/module/hid_logitech/drivers/hid:logitech/*/range file. Does it exist any documentation on this driver ?
Thanks !

I have exactly the same problem (impossible to write in range file):

$ echo 540 > /sys/module/hid_logitech/drivers/hid:logitech/0003:046D:C294.0006/range
$ cat /sys/module/hid_logitech/drivers/hid:logitech/0003:046D:C294.0006/range
270
$ lsusb -s1:4 -vvv | grep bcdDevice
bcdDevice 12.39

So I used ltwheelconf:

ltwheelconf --wheel G27 --nativemode --autocenter 100 --rampspeed 1 --range 540

It works almost well : resulting range is not 540 degrees, but something like 810 degrees. Moreover I get about 200 degrees of dead zone, whatever the configuration I set in games.

So I have to play with the driver default range of 270 degrees. Except the range, everything is working well.
