1st Bartop Arcade Cab build.

so I have a Jamma harness connected to a Jamma to usb converter plugged to my RPi3. When I run emulation station and go to configure the controls, everything works except the up and left on both P1 and P2 controls. the Jamma to Usb converter stated that it was compatible with the pi. what gives? I did plug the usb to a laptop and it does recognize all buttons and joystick movements in the control panel settings. When I connect the usb to the pi, no luck. the left and up are.not recognized but all other buttons are...
anyone run in this before? should I just use the Xin Mo 2 player controller to wire up the bartop?

@vertigo5oh is this seen as a controller or keyboard?
