I ported the abtn driver (sys/dev/adb/adb_buttons.c) from NetBSD. That might be of some help to you. It's a trivial driver, so doesn't contain everything needed, but should be a useful start. - Justin On Wed, Mar 14, 2018 at 10:08 AM, Evan Sabin <memereferencehere@gmail.com> wrote: > I suppose I=E2=80=99ll just play around until I get things to work.
