To report only Single Touch events(primary touch) to a multitouch capable Linux
kernel (2.6.38 or 3.x.x or 4.x.x) as mouse events, use the FORCE_SINGLE_TOUCH
option. The primary touch events will only be reported to the system, while the
other touches are discarded. Enable this capability by uncommenting the code
that defines FORCE_SINGLE_TOUCH in elo_mt_input.c kernel module source code,
build and install the kernel module.
