Was delivered to the USB hub with an external power supply (4 amperes), a USB 3.0 cable and a comprehensive German-language manual. The non-existent piano finish, I feel as an absolute plus. A dust collector including fingerprint collector less ;-)
Commissioning is easy to carry out, fortunately without any necessary driver repositories or installation orgies. Plugging in and ready.
Connection
When operating under Windows 7 or 8 (32 or 64 bit), Linux Ubuntu 4.12 LTS (32 or 64 bit) or SuSE 12.1 (32 or 64 bit) simply plug into an available USB 3 connector and already is a bandwidth of USB 3 at 10 other ports available. But this should always be observed that the 10 USB ports must share the maximum speed of the USB port on the connected device. Therefore, the hub can only be as good as the USB port on the device itself and also provides only the total bandwidth of a USB port! Anything else would be a miracle.
Operation on TV androids with USB 2.0 output (Rikomagic MK 802 S IV and Hard Kernel ODROID U2 and X2) went without any problems with me.
9 of 10 USB ports can be used in groups of three other separately on and off. This is quite handy because I just let off via a switch quite times unneeded USB hard drives / devices, instead of removing it every time from the hub.
Is still a USB charging port, which allows one to 2.1A for charging a battery-powered device to the hub. My Sony Xperia Tablet S and also a HTC One Mini 2 smartphone can be so loaded easily.
It can be easily connected USB 2.0 compliant devices, which really works. A fixation on USB 3 is not given. That's a plus.
On Linux, however, can lead to problems if 3 connecting older devices are only connected with USB 2 to USB. In case I had already repeatedly on some devices and is completely independent of the used USB port (whether PC or HUB directly). With me germinate because the suspicion of not quite clean threads USB driver files on Linux.
Power Supply
Partial operation is possible even without the included power supply. USB devices that do not require a lot of power to come up with the supply by connecting the device (PC, Android box) quite rightly. I have the case of a USB HDD, the persistently denied your service, provided that the separate power supply is disconnected.
Power Consumption
The power consumption of the power supply was a EM600 (not calibrated) instrument detected. The power supply unit with an attached hub consumes about 1.2 watts at idle. I've seen better.
Summary
Convenient USB 3.0 Hub with many ports and full backward compatibility.
