I have had this annoying problem and had no idea what was going on until I stumbled upon forums somewhere after many Google searches. My Anker USB 3.0 hub would cause my bluetooth keyboard/mouse receivers to become unresponsive at random times (in retrospect at times when the hub was placed close to the Macbook Pro). I placed the hub at some distance from the MBP and voila the issue went away!
