The L button on my PS2 controller does not work on Nintendont

[N4VI305]

I tried to use different "controller.ini" that already exist, and I even tried to create one from the HID test but none of them make the L button work (the controller is new and the L button works perfectly), I connect my PS2 controller from a usb splitter

if pressing the l button doesn't change numbers on hid test then it wont work on nintendont either, also usb hubs are not supported officially just connect it directly to the wii/wiiu usb ports.
