3.0 USB hub, which will only work if he wants to?

I've placed this 3.0 USB Hub bought to cover up for the laptop fast data on two external hard drives can.
On the hard drives, it is not: Proof directly connected to the PC to function this properly!
About the Hub there constantly problems: First, the PC recognizes the stroke, then again not. Then the hard disks have switched off, or have "alarms" on its given ... etc. (There is also an extra connection for 5 volts with "small transformer": all functions or dysfunctions, with or without additional energy equal ....)
On the website of this company This 3.0 hub is not performed if there is a driver for it, for me is not been comprehensible (... the first time the driver has been detected after the plug?)
I highly recommend this device, which is also a little on big plus is impractical from the terminals, do not recommend!
