14 mode is listed as follows:

Michal Malýb96d23e2015-02-18 17:59:21 +010018 Currently active mode is marked with an asterisk. List also
19 contains an abstract item "native" which always denotes the
Michal Malýf31a2de2015-02-18 17:59:23 +010020 native mode of the wheel. Echoing the mode tag switches the
21 wheel into the corresponding mode. Depending on the exact model
22 of the wheel not all listed modes might always be selectable.
23 If a wheel cannot be switched into the desired mode, -EINVAL
24 is returned accompanied with an explanatory message in the
25 kernel log.
26 This entry is not created for devices that have only one mode.
