| KernelVersion: 3.2 | |
| Contact: Michal Malý <madcatxster@devoid-pointer.net> | |
| Description: Display minimum, maximum and current range of the steering | |
| wheel. Writing a value within min and max boundaries sets the | |
| range of the wheel. | |

| Date: Feb 2015 | |
| KernelVersion: 4.1 | |
| Contact: Michal Malý <madcatxster@devoid-pointer.net> | |
| Description: Displays a set of alternate modes supported by a wheel. Each | |
| mode is listed as follows: | |
| Tag: Mode Name | |
| Currently active mode is marked with an asterisk. List also | |
| contains an abstract item "native" which always denotes the | |
| native mode of the wheel. Echoing the mode tag switches the | |
| wheel into the corresponding mode. Depending on the exact model | |
| of the wheel not all listed modes might always be selectable. | |
| If a wheel cannot be switched into the desired mode, -EINVAL | |
| is returned accompanied with an explanatory message in the | |
| kernel log. | |
| This entry is not created for devices that have only one mode. | |
| Currently supported mode switches: | |
| Driving Force Pro: | |
| DF-EX --> DFP | |
| G25: | |
| DF-EX --> DFP --> G25 | |
| G27: | |
| DF-EX <*> DFP <-> G25 <-> G27 | |
| DF-EX <*--------> G25 <-> G27 | |
| DF-EX <*----------------> G27 | |
| G29: | |
| DF-EX <*> DFP <-> G25 <-> G27 <-> G29 | |
| DF-EX <*--------> G25 <-> G27 <-> G29 | |
| DF-EX <*----------------> G27 <-> G29 | |
| DF-EX <*------------------------> G29 | |
| DFGT: | |
| DF-EX <*> DFP <-> DFGT | |
| DF-EX <*--------> DFGT | |
| * hid_logitech module must be loaded with lg4ff_no_autoswitch=1 | |
| parameter set in order for the switch to DF-EX mode to work. | |

| Date: Feb 2015 | |
| KernelVersion: 4.1 | |
| Contact: Michal Malý <madcatxster@devoid-pointer.net> | |
| Description: Displays the real model of the wheel regardless of any | |
| alternate mode the wheel might be switched to. | |
| It is a read-only value. | |
| This entry is not created for devices that have only one mode. | |

| Description: Controls whether a combined value of accelerator and brake is | |

| which can do not work with separate accelerator/brake axis. | |
| Off ('0') by default, enabled by setting '1'. |
