why isn’t my kbm working as it’s already plugged to keymander?

What console are you playing on?

Please make sure you are using the Micro USB cable that came in the box as the cable that is connecting your controller to the gamepad port.

Also, be sure to use the power port on the K2 which will require a second Micro USB cable (only one included) on a power adapter (2.4A or greater is preferred).
