usb stays on after shutdown

Dort

Hi ,
I'm using the USB ports to power peripheral hardware.
up until not long ago the USB power would turn off in system shutdown
but a few days ago I've noticed it stopped happening .
now the USB power stays on.
I've looked for an answer online and found many discussions referring to :

1 - Go to Control Panel > Power Options > Change Settings Scheme > Change Advanced Power Settings > USB Settings > and deactivate Selective Suspension;

2 - Go to Control Panel > Power Options > Choose What Power Buttons Do > Activate Settings Currently Unavailable > scroll down to Shutdown Settings > disable Activate Fast Start.

I tried this and it didn't work.
could you advise on any other solutions that could be helpful?
BR,
Dor.
