Sounds like not enough power getting to the hub. Is it hooked up to the usb 3.0 port? If not does switching it over fix the problem? Does disconnecting certain devices from the hub change anything or is it when the hub is the only thing connected?

Is this something recent or has it happened since you bought the hub or laptop?

I am unsure then. If plugging the hub in by itself with only one device and it not working right and if another hub does the same thing unless they are the same model then I would still guess power. If the hubs are working correctly with other computers then it seems like something is wrong with a driver or faulty hardware. Things I would try is maybe trying a linux live cd and boot into it to see if its windows or the computer. If everything works correctly with the live cd I would say maybe the nvidia driver if it is tied into the usb like on my y720. Those are things I would try myself to figure out the problem. I keep usb with a few different live distros to check problems if it's windows fault or the computers.

Try the left USB port (Always on Port), I have the same problem and related problems with USB, when I used the Always on port the problem disappears. Although I think that is not how the USB ports are supposed to work.
