I’m using Lakka in my arcade cabinet, which uses a 16-button, two-joystick kit and USB controller. Previously it worked fine in MAME under Mint 17. In Lakka everything works fine except the joysticks report as the same two axes when mapping the directions for player one and player two. So moving player one moves player two, and vice-versa. I tried clearing the digital stick mappings, mapping the sticks as analog, enabling the option to convert analog to digital, and using the left joystick as the left analog and right joystick as the right analog but it exhibits the same behavior. Is this a bug? Is there a workaround?
I filed a bug report here:

New information in the bug report:
The USB controller board for the button/joystick kit reports in Retroarch as “THT Arcade console 2P USB Player (#0)”.
