Actually, X11 does know of joystick presence. See udev autoconfiguration backend sources: https://gitlab.freedesktop.org/xorg/xserver/-/blob/master/config/udev.c#L254 But... FreeBSD does not have sysfs and most likely will never have, so libu= dev is a shim which uses libmagic-alike heuristics taken from xf86-input-evdev = to detect device type and type tag based on device's evdev descriptor:=20 https://github.com/FreeBSDDesktop/libudev-devd/blob/master/udev-utils.c#L410 It is highly likely that this logic was not ever tested and just does not w= ork in joystick part. So we can try to fix it or e.g. steal from alternative udev-shim library: https://github.com/jiixyj/libudev-fbsd/blob/master/src/libudev.c#L245 --=20 You are receiving this mail because: You are the assignee for the bug.=
