Please confirm if you are using the BIOS version 0353
It is necessary to uncheck the USB S4/S5 power option from Power tab.
The orange USB 3.0 port always has power even when the NUC is off. It is necessary to use a blue USB 3.0 port.
I'm using BIOS version 0353 and i have unchecked the USB S4/S5 power option from Power tab but i still have power on all usb ports when i restart the NUC.
When the NUC is shut down there is in fact power on the orange usb port but shutting down does not solve my issue.
I need a way to restart a device that is powered by the NUCs usb ports (4 devices connected to 4 usb ports) by restarting the NUC. is that possible?
The orange USB port has always power, it does not matter if the NUC is On or Off. In your case, it is necessary to plug the portable spectrum analyzer to any other USB port. (Blue) It is not possible to change this setting.
Disabling the USB S4/S5 power option from Power tab solves the issue with the rest of the USB ports (Blue)
