Hello! My usb ports still powered after shutdown. (bios 11.02)
I tryed to load bios defaults. It no luck. Than I configured bios for the second time and set:
- Deep Sleep - Enabled in S5 (in os win10 fast start uncheked)
- Turn on onboard leds in S5 - disabled
- PCIE devices Power On - Enabled (I need WOL)
And this no luck too...
Usb power is off only when "PCIE devices Power On" set do "Disabled" but in this case I have no ability to use wake on lan function. So what I have to do to use WOL and power off my usb devices at the same time? Maybe it depends on the shematics of the motherboard (usb power lines joined with lan port)?
Help me plese, it is very important point for me. Thanks!

P.S. In my old MB Asrock b75 pro3 I have the same problem and I have installed pci to usb extension card and it solved my problem but I dont want to do the same on brand new hardware.

Hi Sergmasharov,

Thank you for your post.

Deep sleep and PCIE device power on are the conflict options.
Deep sleep will disable all standby power, but PCIE device power will require the LAN to be kept on standby.

Please contact the USB device vendor to check if their device can cut the power when the system is off.

All the best
ASRock TSD
