that happens with my gigabyte GA-Z77MX-D3H
i haven't checked the provided Amps to see if it's even worth to use as a mouse charger... but it's retarded as it leaves my mouse LEDs always on and that bothers the hell out of me.
There's no option about that on the mother board... i now turn off the PSU after a shutdown, but that's even more retarded
also, all options to wake computer are off.
any idea how to get rid of that?
also, only devices previously connected are affected. if, after the shutdown, i unplug the mouse and plug it back in, the lights go out.
and in my case it's not windows, but linux.
