Hi,

I'm struggling to assign my arcade controls to the virtual xbox controller using xboxdrv.

For the most part it is fine and I have most buttons working ok.

Unfortunately 2 of the buttons I wish to assign are not giving a name when using evtest, so I can't assign them.

When I run evtest most of the buttons come back with the expected 'BTN_THUMB' etc. But these two buttons are coming back with (?). they have unique event codes, but no name I can use.

I get the following for one of them to help you understand what i mean.:
"type 1 (EV_KEY), code 302 (?), value 1"

Is there any way I can use the code '302' instead of the name in xboxdrv?

I've tried just putting 302 and "302" as below, but without success:
--evdev-keymap BTN_TRIGGER=a,BTN_TOP2=b,"302"=x,

If not, is there a way of assigning a name to that event that I can then use?

Any help greatly appreciated, as If I can't get a workaround, It would mean some re-wiring of the controls..... last resort this far in! haha.

Thanks

This reports a keyboard button press, not a joystick button. Why don't you post the command line you use to start xboxdrv ?

Thanks for your reply. I'm using an UltraStik 360 with the buttons wired into the joystick. I'm trying to emulate a keyboard for Daphne. I think the joystick emulates key presses from the connected buttons.

I have the code in runcommand-onstart.sh and what i have is working so far, I just need to sort those other two buttons. So far I have the directions, key 1 for 1 player, key 5 for coin and space for action all working from the joystick buttons.

Here's the code i have so far:

Fixed the problem.
By putting KEY_#302 in place of where you would put BTN_THUMB for example, works.
