I have a Corsair K95 keyboard, Corsair M65 mouse and a Razer Tiamat 7.1 headset. After shutting down the power on my rig, they would still have all their lights on. Now the power consumption doesn't bother me, but the bright lights at night do! And the fact that the keyboard lights attract the attention of my young children like moths to a flame. They then start banging on the keyboard and mess with my setup.
This problem has plagued me for over a year now (with a number of previous mice and keyboards), and I finally figured out how to fix it. Most of the posts I have found suggest enabling ErP in the BIOS. My Asus motherboard (P8Z77-V) has this option as shown below (under Advanced menu, APM...)
Note - this setting also disables things like Wake On LAN (WoL), and other means of power up as shown above.
This setting is supposed to disable any USB power after you shutdown. However no matter what, it didn't seem to make any difference. When I shutdown my rig, the gaming headset and keyboard were glowing like hell. I updated my BIOS to the latest version, and screwed around with a bunch of BIOS settings and nothing helped.
But it wasn't the BIOS causing the issue now, it was Windows 8!
In order to get this to work you need to make one small change in Windows 8:
Go to Control Panel ---> System & Security ---> Power Options and select "Choose what the power button does" from the menu on the left.
1. Select "Change settings that are currently unavailable"
2. Un-tick "Turn on fast start-up"
3. Save changes.
4. Power down and voila your pesky USB devices no longer stay powered on :)
