9	What:		/sys/bus/hid/drivers/logitech/<dev>/alternate_modes
10	Date:		Feb 2015
11	KernelVersion:	4.1
12	Contact:	Michal Malý <madcatxster@devoid-pointer.net>
13	Description:	Displays a set of alternate modes supported by a wheel. Each
14			mode is listed as follows:
15			  Tag: Mode Name
16			Currently active mode is marked with an asterisk. List also
17			contains an abstract item "native" which always denotes the
18			native mode of the wheel. Echoing the mode tag switches the
19			wheel into the corresponding mode. Depending on the exact model
20			of the wheel not all listed modes might always be selectable.
21			If a wheel cannot be switched into the desired mode, -EINVAL
22			is returned accompanied with an explanatory message in the
23			kernel log.
24			This entry is not created for devices that have only one mode.
25	
26			Currently supported mode switches:
27			Driving Force Pro:
28			  DF-EX --> DFP
29	
30			G25:
31			  DF-EX --> DFP --> G25
32	
33			G27:
34			  DF-EX <*> DFP <-> G25 <-> G27
35			  DF-EX <*--------> G25 <-> G27
36			  DF-EX <*----------------> G27
37	
38			G29:
39			  DF-EX <*> DFP <-> G25 <-> G27 <-> G29
40			  DF-EX <*--------> G25 <-> G27 <-> G29
41			  DF-EX <*----------------> G27 <-> G29
42			  DF-EX <*------------------------> G29
43	
44			DFGT:
45			  DF-EX <*> DFP <-> DFGT
46			  DF-EX <*--------> DFGT

48			* hid_logitech module must be loaded with lg4ff_no_autoswitch=1
49			  parameter set in order for the switch to DF-EX mode to work.
