| 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. |
