Hello. My point is how to turn off the USB power supply when the computer is turned off. I have a lot of devices hooked up and there is a Christmas tree mouse camera keyboard everything lights up even after turning off the computer. My only weapon is to keep my computer from the socket. And so even several times a day and I saw that it can even be dangerous. I was looking for google but I did not know anything. I also have a Lenovo Y700 laptop and I could turn it off in the program. Maybe there is such a program or you know how to do it in Bios. I mean a desktop computer. My motherboard is the P67A-D3-B3 from Gigabyte. I am asking you for help or other people who know how to turn off USB power after turning off the computer. I would like to add that every time you turn it off from the socket or on the switch some current seems to click and in the end maybe something will burn like that.
