0013 Description: Displays a set of alternate modes supported by a wheel. Each
0014 mode is listed as follows:
0015
0016 Tag: Mode Name
0017
0018 Currently active mode is marked with an asterisk. List also
0019 contains an abstract item "native" which always denotes the
0020 native mode of the wheel. Echoing the mode tag switches the
0021 wheel into the corresponding mode. Depending on the exact model
0022 of the wheel not all listed modes might always be selectable.
0023 If a wheel cannot be switched into the desired mode, -EINVAL
0024 is returned accompanied with an explanatory message in the
0025 kernel log.
0026 This entry is not created for devices that have only one mode.
