@kimmykaroo Hi ! Saw your message on IRC, but couldn't answer at that moment. Can't reach imgur from work, but I remember seeing it was the right button from the lowest pair of buttons right ?
I personnaly set it up to select, HK being the side button (I own a tankstick)
Could you try running evtest
and make sure it's not doing any "down" event ? I'll try to check at home later today.
