I have a issue with my Z87E-ITX motherboard where if i connect up a powered USB3 hub (im using HooToo HT-UH005) i cant turn on the computer. I press the power button and nothing happens. If i unplug the power to the USB3 hub but still leaving it connected to the motherboard, the computer startsup fine.
The computer works fine if i connect the external power to the usb3 hub after the computer is started up.

Anybody see this issue before?
