Oops...

On motherboards with jumpers you have choices like: +5v/+5vSB

+5V is supplying 5 volts from the normal running power supply, which
will/should drop to zero volts when the computer is not running
(switched off, sleep mode, hibernate mode, standby mode).

+5VSB is 5 volts from the stand-by supply, which always has 5 volts on
it, whether the computer is on or off.

BIOS/UEFI controls for the USB supply should work in the same way.

It's possible for the stand-by supply to be a bit weak and unreliable
for some devices.
