Hi
I am using a Aorus X570 ultra and wanted to ask if it is possible to cut power to the USB ports (or at least one) if the computer is turned off.
I am using a Master/Slave power plug solution and it uses a USB cable to detect if the computer at Master is turned on and will decide this way, if monitor and speakers get power or not.
However it always detects the PC as "on", also some devices I connected to the PC (Tandberg RDX, mouse) keep getting power from the PC.
I didn't find an option to turn this off.
Is there any?

Greetings,
Did a quick pass of your user manual.
Look at BIOS > Settings > Platform Power > ErP
Enabling this might work.
Boot Menu heading > I haven't tested the USB support options (Full, Initial, etc), but believe this only applies to detection during pre and POST boot to OS and not power.

Hi, sorry for the late response.
Thank you for the input. That option was already off. I was looking into USB settings, for some reason it never came to my mind to check the system/power-section.
I'll try to activate it, see what happens.
Thank you.
Another idea I had was to put a passive USB hub between these devices (master/slave, mouse, keyboard) and the computer, that worked for an external USB head set, my old hub was just rubbish so I didn't test it for the rest. I'm waiting for a new one currently.

... yes, turning on the ERP was the right thing to do.
I DID stumble across it once, but not read carefully it seems.
Thanks again.

Sure. Glad I could help. 8)

Just for info for everyone trying this ... turning off ERP caused something else to happen: After waking up from ERP, the integrated Bluetooth adapter won't work anymore, it won't show up in the device manager (not even as unknown or deactivated).
The solution: turn off ERP
The workaround: After a hard reset, cut the power to the PC completely for a few seconds. That resets the device.
Then again ... if you usually turn off the power completely, you won't need ERP anyway.
I read somewhere else that also the WLAN adapter is affected, but I can't conirm that, I work with LAN anyway.
I use the latest BIOS F12e, but this error has been present since at least the end of last year.
