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?

YouTube came up with a gigabyte specific video straight away when I
entered "turn off powered USB"

Have you also banned yourself from dealing with Google?

:-p

I generally can't be bothered with videos. Prefer text.

But thanks for the heads up. Turns out you have to enable ERP. Whatever
that is. Obviously just me, but I'd expect any such settings to be in the
USB section of the BIOS.

ERP is the directive that states how efficient computers should be in in
their "off" state. So is the place to find settings for reducing power
consumption by disabling USB ports (and other devices) when off.
