- What: /sys/bus/hid/drivers/logitech/<dev>/range
- Date: July 2011
- KernelVersion: 3.2
- Contact: Michal Malý <[email protected]>
- 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.
- What: /sys/bus/hid/drivers/logitech/<dev>/alternate_modes
- Date: Feb 2015
- KernelVersion: 4.1
- Contact: Michal Malý <[email protected]>
- 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.
