there was a report from a user who saw a series of disconnect/connect
until X11 was started up. and of course most of the time the device
was disconnected when X11 fired up. the workaround he found was doing
cat /dev/input/event3 > /dev/null 2>&1 &
immediately after the touchscreen was detected. this prevented the device
from doing those disconnect/connects...ie. as soon as some process has the
event interface open the touchscreen is stable.
