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.
