Very good - LED unnecessary

Stands steady on 4 small rubber studs. Data transfer rate properly. Devices that sometimes cause problems with my front port, are reliably detected. The sockets are stable and precisely.
The only drawback is the blue LED that lights up even when the PC. On my board, the power supply of the USB ports has been switched off can not be disabled, unfortunately.

Overposting would be a possibility. Otherwise, here is the Remedy for power saving fanatic:
Among the 4 rubber nubs on the bottom there are 4 screws. This unscrew. The board with USB ports and LED can now be found easily. There is nothing stuck or fastened with plastic tabs. The LED is soldered on the board. To them "off" it is enough to bend a little back and forth until it crunches easily or creaks. If necessary, the USB port Make sure that the LED is actually broken. Now the PCB clean use, tighten screws and stick rubber studs again.
That one thus forfeited any warranty claims should be clear, should the price of the device but its bearable.

Addendum:
The partially criticized quality of USB ports I can not understand. Possible Cause: The hub is chamfered at its top. The tricked USB plug slightly oblique, thus at right angles to put the top. If you hold by force, possibly breaking the plastic frame of the socket.
The sockets are perpendicular to the tabletop. So Upon plugging the USB connector vertically and not at an angle.
