While not as polished as Linux’s evdev or Windows XInput, it is sufficient for many retro gaming, emulation, and custom embedded applications. Future improvements could include better force feedback and wider device compatibility. ucom gamepad driver

Unlike Linux’s joydev or hidraw , ucom treats certain gamepads as virtual serial devices that report button and axis states through structured HID reports. The driver stack typically follows this hierarchy: int fd = open("/dev/ujoy0", O_RDONLY); struct ujoy_event ev;
