Writing a value within min and max boundaries sets the 7 range of the wheel. 8 9What: /sys/bus/hid/drivers/logitech/<dev>/alternate_modes 10Date: Feb 2015 11KernelVersion: 4.1 12Contact: Michal Malý <madcatxster@devoid-pointer.net> 13Description: Displays a set of alternate modes supported by a wheel. Each 14 mode is listed as follows: 15 16 Tag: Mode Name 17 18 Currently active mode is marked with an asterisk. List also 19 contains an abstract item "native" which always denotes the 20 native mode of the wheel. Echoing the mode tag switches the 21 wheel into the corresponding mode. Depending on the exact model 22 of the wheel not all listed modes might always be selectable. 23 If a wheel cannot be switched into the desired mode, -EINVAL 24 is returned accompanied with an explanatory message in the 25 kernel log. 26 This entry is not created for devices that have only one mode. 27 28 Currently supported mode switches: 29 30 Driving Force Pro:: 31 32 DF-EX --> DFP 33 34 G25:: 35 36 DF-EX --> DFP --> G25 37 38 G27:: 39 40 DF-EX <*> DFP <-> G25 <-> G27 41 DF-EX <*--------> G25 <-> G27 42 DF-EX <*----------------> G27 43 44 G29:: 45 46 DF-EX <*> DFP <-> G25 <-> G27 <-> G29 47 DF-EX <*--------> G25 <-> G27 <-> G29 48 DF-EX <*----------------> G27 <-> G29 49 DF-EX <*------------------------> G29 50 51 DFGT:: 52 53 DF-EX <*> DFP <-> DFGT 54 DF-EX <*--------> DFGT 55 56 * hid_logitech module must be loaded with lg4ff_no_autoswitch=1 57 parameter set in order for the switch to DF-EX mode to work. 58 59What: /sys/bus/hid/drivers/logitech/<dev>/real_id 60Date: Feb 2015 61KernelVersion: 4.1 62Contact: Michal Malý <madcatxster@devoid-pointer.net> 63Description: Displays the real model of the wheel regardless of any 64 alternate mode the wheel might be switched to. 65 It is a read-only value. 66 This entry is not created for devices that have only one mode. 67 68What: /sys/bus/hid/drivers/logitech/<dev>/combine_pedals 69Date: Sep 2016 70KernelVersion: 4.9 71Contact: Simon Wood <simon@mungewell.org> 72Description: Controls whether a combined value of accelerator and brake is 73 reported on the Y axis of the controller. Useful for older games 74 which can do not work with separate accelerator/brake axis. 75 Off ('0') by default, enabled by setting '1'. 76
