I suspect it's udev issue. Udev is the system responsible for (among other things) identifying hardware and assigning the proper driver to it. It is sometimes necessary to add explicit udev rules for some obscure hardware to force the system to prefer one driver over another, or to recognize some wierd ass USB device would be perfectly happy being treated simply as e.g. a serial device. One somewhat common situation is explicitly telling udev to tread obscure knockoff gamepads as if they were an xbox controller.
I don't think so, it wouldn't even work if it wasn't recognized as keyboard. It probably is recognized as both a keyboard and a gamepad at the same time. Physical USB devices can (and frequently do) present as multiple devices to the host. For example, a keyboard with a scroll wheel will look like be both a keyboard and a mouse.
