The powered USB ports?

interested in this question, the majority opinion in Google because in the General case, software pitanie no way to disable. when talking about flash drives, in many models when unmounting them the controller turns off the power from the drives, but no more

deveject.exe — can disable the usb controller.

As I understand it is something like a tool to unmount flash drives. In principle, it can be set on other devices, but as they are then enabled programmatically?

Funny. Just last night was looking for an answer to this question, but found none. And today he is in the Q&A.
