Hi all,

Does anybody know how I can disable USB power after shutdown on my ASRock B550M ITX/AC motherboard?

I have already enabled deepsleep in s4 and s5 but this did not help.

I'm not able to enable deepsleep fully. Does anyone have an idea?

If you are referring to things like LED USB devices not powering down when the system is shut down you need to enable ErP in the UEFI, that should fix it.

Yes thats exactly what I meant. I found that online as well, but I can't find that anywhere in my Bios?

Do you have any idea where I can find it?

If you don't have an ErP option you'll need to contact Asrock support to see if they are calling it something else or have a firmware image they can send you with the option.
