I hope i post this question in the right topic...

i need to deactivate the power supply to all usb ports after the fitPC has been shut down. The bios ( curr. version) does not seem to provide any parameter for that issue.
Unfortunately Google couldn´t help me. All suggested solutions ( deactivate quickStart in the engery Settings etc) didn´t work.

(OS: Win 10 Pro x64)
Has anyone had a similar problem before or can give me an hint?
I would really appreciate it.
