I am having a helluva time trying to find a good USB 3.0 hub that won't interfere with the Magic Trackpad.  I have done troubleshooting, and confirmed the 7-port HooToo UH04 hub (when plugged in to AC power) causes the Trackpad to sputter and misbehave.  I have moved the hub as far away from the computer as possible, with little relief.
