Hello,
I recently bought a Logitech Cordless Desktop S510 with Remote which
works nicely, except few extra keys for which I can't get any events.
After some investigation and googling I found out that all these
non-working keys had keycodes bigger than or equal to 4120.
As there are some patches floating on the net which try fix the problem
by making the keycode suitable for mappable area, but after trying one
these, I still can't get any usable data (except the debug message ;))
from my devices.
I have attached the patch and hopefully someone can point out what I am
doing wrong.
Cheers,
Priit
