I have used a joystick on FreeBSD. webcamd takes the device.

you can set up rules to give your regular used access, or I think it's just as
easy to add your user to the webcamd group.
so, you can read the device. a game engine that works on FreeBSD such as SDL2
has the code to read it.
Here's a simple example: using libevdev.h.
(defines in /usr/local/include/linux/input-event-codes.h)
int nbuttons = 0;
fd = open("/dev/input/event10", O_RDONLY | O_NONBLOCK);
rc = libevdev_new_from_fd(fd, &dev);
for (i = BTN_JOYSTICK; i < KEY_MAX; ++i) {
if (libevdev_has_event_code(dev, EV_KEY, i)) {
printf("%d - Joystick has button: 0x%x - %s\n", nbuttons, i,
libevdev_event_code_get_name(EV_KEY, i));
++nbuttons;
}
}
0 - Joystick has button: 0x130 - BTN_SOUTH
1 - Joystick has button: 0x131 - BTN_EAST
2 - Joystick has button: 0x133 - BTN_NORTH
3 - Joystick has button: 0x134 - BTN_WEST
4 - Joystick has button: 0x136 - BTN_TL
5 - Joystick has button: 0x137 - BTN_TR
6 - Joystick has button: 0x13a - BTN_SELECT
7 - Joystick has button: 0x13b - BTN_START
8 - Joystick has button: 0x13c - BTN_MODE
9 - Joystick has button: 0x13d - BTN_THUMBL
10 - Joystick has button: 0x13e - BTN_THUMBR
