Works as a hub, but confuses my motherboard
On the upside, it works: once I’m booted, I can plug in devices (USB2 or USB3) and they’re detected by the computer. The charging ports behave as expected. The package is attractive and functional. So there’s that.
But unfortunately I can’t boot my computer with it plugged in! I have to unplug it, boot, and THEN connect it. It’s possibly something to do with my motherboard (Asus Z87 MAXIMUS VI FORMULA), or it’s possibly something to do with the way that the device identifies itself as a hub, but my computer just “hangs” at the POST screen if I’ve left it connected when I press the power button: more than a little irritating!
