When power is off, i would like to stop power of all USB (even usb-c).
I succeded in stopping power of rear usb3 but not the usb-c and not the front usb ports.
Apply the following BIOS settings:
Advanced > Devices > USB set the Portable Device Charging Mode to OFF.
Advanced > Power > Secondary Power Settings uncheck the USB S4/S5 Power (Deep S4/S5 should be set to Disable, otherwise this setting is hidden and Disabled)
Firstly, I would like to thank you for your answer.
The new configuration works except for the rear usb-c and the front yellow usb slot.
At first, it seemed to work as usb-c was off. But as soon as I tested the front yellow usb slot, both slots (front yellow usb and rear usb-c) are powered.
Are you talking about the state immediately after you plug in the NUC or are you talking about the state after you shutdown or suspend? I believe that the former state will always have the ports powered (you have to complete a full POST before the BIOS will program them to power off) and the latter state will (ok, should) follow the BIOS configuration.
1. I don't have NUC BE , however I've checked this on two other NUCs I have: NUC HV and NUC DN. Those NUCs have the same Visual BIOS as your NUC has. After applying setting in BIOS as per my post above, there is no power in USB ports, neither USB - C and neither the Charging USB.
2. So, if you applied correctly the settings and still you have power, I suggest that you should update your BIOS to the latest Version: 0085 using BIOS Recovery by Power Button Menu Then set the correct settings for USB and try again.
We are currently reviewing the technical product specifications for this device and investigating this behavior.
I will provide an update in the thread as soon as possible.
