13Description:	Displays a set of alternate modes supported by a wheel. Each
14		mode is listed as follows:
15
16		  Tag: Mode Name
17
18		Currently active mode is marked with an asterisk. List also
19		contains an abstract item "native" which always denotes the
20		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.
