I have tried looking in the bios but no luck in finding a power saver/usb port power.

Just today I purchased both K55 and Harpoon new. Love the RGB but there seems to be a slight problem. The backlit will not turn off with my PC like the mice/mouse does. I have both USB's plug into the motherboard. My case does have a USB port but I find it kind of weird if I needed to resort to that. Is there a way to set the keyboard to shut off with the PC. I even tried manully turning off the keyboard with the brightness button but still no go. Is there a solution?
