Happened to me while playing with a couple builds, including Xenial Mate. On one build it took a couple minutes for the OS to recognize the mouse/keyboard. Like a previous user, I figured power related. Had a usb2.0 powered hub from RaspPI gear. No problems since I started using the hub. Sorry, I didn't research any further so maybe other suggestions will solve the issue without having to use a hub.
