I just got a new gaming keyboard. It the Genius Manticore. It has two usb plugs and two usb ports. I don't know why the keyboard has two plugs. I've look at the manual and it don't say. This is my the first keyboard to have this.I've had a few gaming keyboard so I'm wondering if it need more power to run all it functions. It has a lot of really cool extra stuff. If you know why please let me know. Thanks.
