1. Sometimes after restart of Win 7 power is off, should be on ! if the power button is not used !

2. Often usb-sticks connected do not appear in windows, must be disconnected and new connected.

This device for 50 € is crap ! I tried other 7 port hubs, they have other faults.
You must pay 100 € / 100 $ to get a good one without defects !
Problem are the chips inside, at 7 port hub you need more than one and according to experts this is the problem so they recommend only buy 4 port hubs.

I see the issue here again.

The device has only 3,3 A, much too less for 7 ports plus 2 ports for current.
USB 3.0 has max. 900mA for each port, so you need at least 5 or 6 A.
The producers always want to save money,
And the power supplies about 5 or 6 A you have to pay only about 50 € or $ for !
Beside that the chip problem is separate from that / malfunction of some ports as mentioned above.

For me it is a cheap china product !
