USB Power

UDOO X86 Ultra. I need to unplug the ac power on USB ports when the UDOO is unplugged or suspended.
How can I do that?

Thanks in advance

 

According this discussion the "ErP Ready" setting in uefi set to ON should do the trick: https://www.udoo.org/forum/threads/windows-10-power-management-issue.9369/

 

Thanks a lot waltervl to show me the solution.
I have installed the 1.03 firmware, but unfortunatelly I can't find the ErP Ready menú.

Could you show me the path?

Thans in advance

 

I have received a response from the lead engineer on this topic. The USB ports are fed by the fixed 5V_ALW (always on power). It is not possible to turn off with a setting.
