The whole point though is for that to also be a charger, though I have to
say I'm not greatly impressed with their efficiency.

One thing I have also found is that for example, if I use it to power some
dongle on my TV, all sorts of crud gets into the supply and power wall
warts are better, but don't use the el cheapo ones as they generally buzz
or create excessive RFI or both.

As for controlling them on or off. The guy who built my machine said it
was a series of jumpers on the mother board, but I never asked him where
they actually were, sorry!

That’s not for having it off when the system is turned off,
just for enabling or disabling it and which connector it
comes out on when you don’t want it on the back panel.

On the PC desktop here (Gigabyte MB) the USB power is on at all times the
PC is plugged into the mains. The separate web cam has a couple of LED
indicators. I assume this is under BIOS control, but can't find a
setting.
But then the BIOS uses all sort of acronyms I don't understand.

Any easy way of disabling this? So USB power only comes on when I boot
the
PC?
