Keeping USB ports powered up when the PC is shutdown is done for other features like turning on the PC with the keyboard and mouse.

Before keeping USB ports powered up became common, some boards had a jumper that would enable or disable the power to the USB ports. That would be an acceptable solution for many users IMO.

One persons great feature is another persons headache.

O.k. thanks. It seems there is no elegant way to get disable this feature. A simple bios on/off option would have been nice.

Supplying power to the USB ports when the PC is shutdown is considered a feature, and is done by design.

You can try setting Deep Sleep to Disabled in the South Bridge Configuration but I cannot guarantee it will work.

Otherwise Xaltar is right.

You can get a USB hub with switches for each port and connect your USB speakers to the hub.

To my knowledge there is no way to fully power down an ATX system other than to turn off the power to the power supply itself. ]]> Sat, 05 Sep 2015 04:50:56 +0000 https://forum.asrock.com/forum_posts.asp?TID=772&PID=3503&title=usb-power-h81mhds#3503 https://forum.asrock.com/forum_posts.asp?TID=772&PID=3500&title=usb-power-h81mhds#3500 Author: deezr
