“Very handy for adding peripherals to a R-Pi Zero. It really is USB 2.0 despite the white USB connectors (normally indicating USB 1.1).
The power switch disconnects power from the host port to the 4 downstream ports, but does NOT disconnect external power from the downstream ports. That can actually be useful for powering peripherals from a 5V adapter to avoid overloading a R-Pi Zero for example. The switch can even be used to cut power to the Pi for rebooting etc.”
“Excellent little micro usb hub. Good for things like pi 2 zero that only has one usb port.
I use it for connecting miltiple joysticks for multiplayer retro gaming.”
