If the KeyMander is connected to a PS4 using the DualShock 4 Slim controller and it does not respond to the keyboard and mouse, there are two things to check. First, make sure you have enabled USB Communication in the System Settings menu. Go to Settings > Devices > Controllers > Communication Method and select Use USB Cable.


Next, disconnect the USB cable from the KeyMander from the controller and wait a few seconds. Reconnect the USB cable. If the cable is a USB charge and sync cable, the PS4 controller should turn on and display a yellow light. If it is a charge only cable, it will show a blue light which means it is still in wireless mode and does not recognize the cable. In this case, use the included 3-ended cable as shown here for testing.
