It is unfortunate that there is not a second USB port on the cable since not all USB 2.0 devices are capable of mastering it. However, there are no issues with USB 3.0. My speed with USB 2.0 is 30 mb, and with USB 3.0 it is 50-60 mb at first, but then it dips to 25 mb; why this happens I do not know; maybe it's just me.
