Internal usb hub / card reader / expansion cards with physical On/Off Switches

I want to add the following feature request:

I would like to have an internal usb hub and/or card reader with physical On/Off Switches for each hub or card slot.

And maybe you can also turn on / off all hubs and card slots using just one button.

Of course this idea also applies to the expansion cards.

There are already external usb hubs that have physical On/Off Switches:


It would definitely help with the power sipping Iā€™m hearing about. But considering the dimensions of the expansion cards, it might be difficult. But it would be interesting to see someone fit a toggle button in there somewhere.

a DIP switch on the circuit board (and matching holes in the case) might be all it takes. However, signal integrity can be a issue.
