However I am quite unsure where to even start at this point. I have a usb lamp which I specifically bought in order to turn it off programmatically at a certain time, thus I need to remove the power to its usb port. I am not afraid of the command line or of scripting or changing configuration files. Does anyone know how I can do this from within the operating system? Shouldn't it be possible to cut power to all the USB ports on shutdown? Or even, to determine for each port individually whether it should remain powered or not? There is no option that I can find in the BIOS system settings to accomplish this. Which makes it sort of useless, unfortunately. In the present state it obviously does not power off my other peripherals (monitor, amplifier, desk lamp.) without manually flipping the switch. I also have a power strip that I like to use, which works with a USB controlled relais. I would prefer it if no USB devices were leeching power while the computer is off, while still being able to turn on the computer (and everything attached) remotely through Wake-on-LAN. This seems undesirable to me and it was not the case with my previous computer. Except I noticed that the USB ports keep supplying a voltage even after I shutdown the system. Hello, I just built a new desktop computer using an Asus M5A78L-M/USB3 motherboard with an AMD FX6300 CPU.
