Arduino USB power switching

Hi all,
I am looking for board for Arduino which would switch ON/OFF USB power supply to couple of devices. I found following board - yepkit but not directly for Arduino.

Please would you have any advice if such board already exist or if you have any experiences with your own device? Ideally the board could have 4 to 5 USB ports.

Thank you.

Here is a USB A-A cable with a switch.

I am looking for switch which would be driven by Arduino pins, not the mechanical one.

Here is a relay-control USB A-A.

Ok, thanks for the link.
