How I signalize that a service of OpenRC should start on the hotplugged runlevel?

I have a service called xboxdrvd that is triggered (and only activated/deactivated) by a [udev](https://github.com/ryukinix/xboxdrv-bin/blob/master/61-twin-joystick.rules) rule, however always calling rc-status I got that the service was started on "manual" runlevel:  The hotplugged is not for that type of events? I did read the [gentoo docs], but there is not so much thing on there.
