Title: GA-Z77N-WIFI USB 2.0 mb header power with ErP enabled
Post by: chmooreck on June 22, 2016, 07:52:01 am

Despite setting ErP mode in BIOS (options of Wake op on keyboard/NET become gray/disabled as expected) the USB 2.0 on-board header is still powered up after shutdown.
I would like to have it turned off because I've got LCD display connected to it.

Is this normal (GIGABYTE On/Off Charge feature maybe) ?
Which USB ports are supposed to be turned off on shutdown with ErP mode enabled ?

I've get response from tech support. USB ports are powered all the time. No setting to change it. It's a pity. USB ports power was disabled on my previous board in ErP mode (GA-H67N-USB3). One step backward, at least for me.

I'll make hardware solution: power directly form PSU.
