bool "Support OneTouch Button on Maxtor Hard Drives (EXPERIMENTAL)"

help
Say Y here to include additional code to support the Maxtor OneTouch
USB hard drive's onetouch button.

This code registers the button on the front of Maxtor OneTouch USB
hard drive's as an input device. An action can be associated with
this input in any keybinding software. (e.g. gnome's keyboard short-
cuts)
