[j.p.s]

The KOA2 page turn command data are completely different from the Voyage, as is the event number. See post #1 in this thread for more elaborate description.

To capture the data:

cat /dev/input/event5 > nextpage.dat
^C

cat /dev/input/event5 > prevpage.dat
^C

To turn to the next page:

cat nextpage.dat > /dev/input/event5
