Hi!
I've a z77 pro 4.
There is mouse, keyboard and mousepad connected to the usb ports (all with RGB lightning).
When the computer is shutdown the mouse and mousepad has the light on. This is very annoying since the computer is in my bedroom.

I've tried to change usb ports and set these settings in bios:

Deepsleep -> Tried both S5 and S4-S5
Fastboot -> disabled

I've also unchecked the "fast boot" option in the energy saving settings in windows but still no change.

Is there something wrong with my board?

I know that i can "fix" it by turning on and off the PSU but thats not really an option in my POI.

Please help!
