Power off usb while computer is off?

Hello everyone,
 I bought a Z170 Extreme4 with i5 6700k, I just modded a bit the case adding an usb led strip, that is attached to the usb_1_2 onboard port, but when i turn off the pc the stripe remains still on, that is quite annoying because everytime I turn off the pc I have to unplug it from the AC,
I looked for something like ErP to set to S4/s5 (like adviced in other forums) but I can't find anything realated to Usb 2.0 power in the bios (simple or advanced mode)
the Bios UEFI version is P7.2
Thank you in advance

Yes, it's the Good Night LED option in the Advanced, Chipset Configuration screen.

The ASPM options are power saving options for the PCH (chipset) and the CPU's PCIe lanes.
