  12. Description: Displays a set of alternate modes supported by a wheel. Each
  13. mode is listed as follows:
  14. Tag: Mode Name
  15. Currently active mode is marked with an asterisk. List also
  16. contains an abstract item "native" which always denotes the
  17. native mode of the wheel. Echoing the mode tag switches the
  18. wheel into the corresponding mode. Depending on the exact model
  19. of the wheel not all listed modes might always be selectable.
  20. If a wheel cannot be switched into the desired mode, -EINVAL
  21. is returned accompanied with an explanatory message in the
  22. kernel log.
  23. This entry is not created for devices that have only one mode.
  24. Currently supported mode switches:
  25. Driving Force Pro::
  26. DF-EX --> DFP
  27. G25::
  28. DF-EX --> DFP --> G25
  29. G27::
  30. DF-EX <*> DFP <-> G25 <-> G27
  31. DF-EX <*--------> G25 <-> G27
  32. DF-EX <*----------------> G27
  33. G29::
  34. DF-EX <*> DFP <-> G25 <-> G27 <-> G29
  35. DF-EX <*--------> G25 <-> G27 <-> G29

  38. DFGT::
  39. DF-EX <*> DFP <-> DFGT
  40. DF-EX <*--------> DFGT
  41. * hid_logitech module must be loaded with lg4ff_no_autoswitch=1
  42. parameter set in order for the switch to DF-EX mode to work.
