Hi,

I have a powersaving extension powerbox, which is connected to my USB port.
When turning on my computer it sends a signal to the powerbox, which then
enables the power for whatever i plugged into it's power outlets (printer,
speakers, screen etc)..

Any ways, for some reason on my A7N8X-E there is always power on my USB
ports.. Anyone know how to disable this ??

regards
jorgen

First, did you try all of the USB ports?

Second, what kind of keyboard do you use - PS/2 or USB?

If you only power the USB ports when full system power is available you'll
never be able to Wake the system from a USB keyboard. Which explains why at
least one of your USB ports is powered by standby 5V.

On some motherboards there's a jumper you can move to select the source of the
5V to the USB headers - from a non-standby source or from a standby source.
Check your user manual for "USB Power Select" or something similar...

Correct - this mobo has jumpers to select the power source for each
of the 8 USB ports. Leave the jumper on the port connected to your
powerbox at "+5VSB" and change all the rest to "+5V".
