I cannot have this hub connected to my Dell PC when I reboot as my PC will not boot up at all when it is connected.  While it could be a PC issue, I find it interesting that I don't experiencing the problem when the hub is not connected.  I previously had the 4 port Cyberpower USB2 hub and loved it, but I did not have enough ports for all of my peripherals, however, I have come to regret this purchase.  Again, it could be my PC or maybe I have a defective hub, but I sure wouldn't buy this hub again.
