I'm using a "HuiJia USB Gamepad" to connect a standard N64 controller to my computer over USB. I'm doing this so that I can play games using mupen64plus, which uses the SDL to get input. My problem has to do with the way the adapter deals with C button events. Apparently, the u/d and l/r C buttons are treated by the adapter as joystick axes, so joystick events are generated by using them. But, for some reason, these events aren't recognized by SDL.

It gets stranger - if I cat the output of /dev/input/event5, the event gets printed when a C button is pressed. Furthermore, when I configure SDL to use the /dev/input/event* devices rather than /dev/input/js0, the C buttons are recognized! (Though, this leads to a situation where the joystick can't be calibrated... go figure).

So, I can either have a correctly calibrated joystick with no C buttons or a miscalibrated joystick with working C buttons.

Does anyone have any idea what I can do about this situation? The best outcome would be to force the C button joystick events to appear when using /dev/input/js0.

Thanks!

Have you tried using the xboxdrv driver?

Do you know which driver is currently being used to interface to that gamepad?

I seem to remember that the xboxdrv site mentioned some form of experimental gamepad support, not sure if it was for your device, but maybe its a starting point...
