Atgames aimtrak light gun trigger not mapping

[mickgrill]

Good day,

I hope someone can help me with my issue. I have an aimtrak light gun and an Atgames legends Ultimate cabinet. I setup my aimtrak on my pc first ensuring the buttons were mapped according to pdubs tutorial and verified the settings were saved. When I hook my gun up to the cabinet and calibrate it, the calibration works fine and the gun tracks great. When I go to use it in any game the trigger doesn't work. The trigger does work as an action button however doesn't fire in game. When I go under adv settings and try to manually map the trigger, instead of registering as "Gun 1 B1" it's registering as "kbd P1 B1". I've tried the gun in both the 2.0 and 3.0 USB ports and reconfigured it with the Ultimarc utility, however, nothing is getting the trigger to be recognized as "Gun 1 B1".

Any help would be appreciated. I'm sure it's something stupid I'm doing or missing.

Thanks.
