Mouse light doesn't turn off when computer is off

Question

I've bought a Coolermaster devastator bundle with my new PC. When i shut down the computer, the light on the mouse never turns off. The keyboard lights are off. Both peripherals are plugged with USB. My motherboard is a GigaByte GA-Z97M-DS3H

Any idea why the mouse never shut down? Maybe an option in the BIOS?

Update:

After reading the motherboard manual, i didn't found a jumper to deactivate the functionality. However, it talk about the ON/OFF charge (page 8) in the "Unique Features" part, which is related to a software called AppCenter. I've installed it but the ON/OFF charge is the only features listed in the manual I don't have in the app (tried to explore EasyTune, EZ setup, Smart timeclock, etc... nothing helped).

I've also check the options in the BIOS but i didn't found anything related to that problem.

The BIOS is up-to-date, I can't see what I can do now.

Solution

So I've finally found the option into the BIOS.

I've set ErP to Enabled:

Determines whether to let the system consume least power in S5 (shutdown) state. (Default: Disabled) Note: When this item is set to Enabled, the following functions will become unavailable: PME event wake up, power on by mouse, power on by keyboard, and wake on LAN.

It does not work on my Gigabyte Z97X-UD3H-CF. Which kind of USB ports should I use for my keyboard and mouse?
