Doesn't the '_IOW()' here mean that you need write access to
/dev/ujoy/<n> to use that ioctl() ?

Also, even though I'm partly responsible for the current situation as
porter of the now defunct ISA joy(4) driver
(https://man.openbsd.org/OpenBSD-3.0/i386/joy),  I think one should
think about plugging it into wsmouse(4) (adding a
WSMOUSE_TYPE_JOYSTICK to let applications make the difference). IT
will make supporting them in libinput-openbsd easier.
