Because I didn’t mind whether the controller announced itself as two joysticks with two axes each, or one joystick with four axes. In the software I use it for (a MAME for the Raspberry Pi), I can map a single device’s buttons and axes to several players. I’m a bit surprised with this, though: > $ jstest /dev/input/js0 > Joystick (Xin-Mo Xin-Mo Dual Arcade) has 2 axes (X, Y) because in my case I had four axes, at least using evtest (I don’t remember if I tried jstest as well). What bothered me at the time, though, is that even though the custom driver was made as a kernel module, an entry had to be added in the hid_have_special_driver table in hid-core.c for the kernel to use it, which means, if I understand properly, that the kernel still needs recompiling. Is that normal?
