Incidentally, these powered USB hubs are pure gold if you do any embedded development. Plenty of USB-A ports (of which MacBook Pro owners get exactly zero, because courage, and Tim Cook doesn't have any USB-A devices) — absolute requirement for any embedded development. Powered, so you can run plenty of stuff without additional power supplies. And individual button for switching ports ON/OFF, which is a godsend when you need to reset a device or test a reconnection.
