ASRock A300 USB power

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hey guys I was just wondering if there's anyway to disable the power on the USB ports of the A300 when it's off (shutdown). I've been digging through the BIOS and I cant seem to find the option for it.

Why do I want to disable the power on the USB when the PC is off?

I use my A300 for my arcade1up cabinet and I installed some pretty bright LED buttons/switches which is connected to the PC through USB.

	Are you using latest BIOS? You may also want to check options labeled ErP or EuP. Or maybe disable charging port?

	Yes, I updated the BIOS as soon as I installed win10. Where could I find the options for ErP/EuP in the BIOS? Cause I've checked everything in the BIOS and I don't remember seeing those. All I saw was a USB power config option and that turns off the port completely. I also saw a thread here in the forums suggesting to enable Deep sleep (under the South Bridge) for s5 and s4 but that didn't solve my issue.
