Question Ho do I set the USB ports on Asrock B450 Pro4 to not supply voltage when computer is turned off?

I noticed that my USB audio interface remains on after I shut down the computer, which forces me to unplug the USB cable every time.
I think I've turned off all deep sleep functions in the Bios and remember in the olden days you could choose whether you wanted to still have power supplied to the USB ports while shut down (e.g. for charging a device) or not.
Anyone stumbled upon a setting for this in the Asrock Bios?
 
some users recommend enabling deep sleep to turn off the USB power. Some say it works and others say it doesn't.

You could always turn off the PSU switch.
 
Yeah, in ASRock BIOS menu, there's a feature called Deep Sleep. It will shut motherboard power down and reduce phantom load.
 
Thank you guys for the suggestion to enable Deep Sleep. It did solve my problem.
However, am I the only one that associates the term "Sleep" with a low power mode of operation, something that does not require a full re-initialization (cold boot) to return to normal operating mode?
Also, why do they recommend for compatibility and stability to not do a proper shut down that cuts power to everything? (see pictures on the right) I miss the old days when the power button was a proper switch mounted on the mains.
