Hi,
I configured my M2-ATX power supply to keep permanently the +5V power in order to use the standby mode on Intel D945GCLF2 motherboard. I'm using every day my car so I don't have an issue with the battery.
My concern is that the USB ports are powered permanently and I didn't find a way to disable the usb while the system is going in standby. All my usb peripherals are powered permanently.

What options do I have. Is there a way to disable the usb port?
I the past I used hibernate mode but I don't like the boot time period.

Thanks,
