IIUC there is no point to trying to find a USB *THREE* port for a mouse
or keyboard, right? USB TWO is plenty. Because so little data is
transmitted.
What about a camera?
I know it uses a lot more, but even at the highest reolution, is it more
than USB2 can easily transmit?
What about a camera whose video will never be showing on a anything
bigger than a 20 or 24" monitor?
BTW, just for curiosity, do they sell at consumer prices a camera good
enough to show a picture on a movie theatre screen. maybe 10 feet high
by 30 feet wide. Would that be helped by USB3?

If I were going to this I would use Ethernet POE cameras and at least a
4 port POE switch. The cameras could then be 4k or better if you wanted
that much resolution, plus night vision. I would not even consider USB.

to slightly better devices. The $50 webcam at the bottom does
a surprisingly good job, but it is fixed focus and highly unlikely
to serve any purpose except Zoom.
