The USB 3.0 Hub works under Windows 7 instantly without driver installation. The data transfer from connected external hard drives is identical to that of a direct connection. At this stroke I have another USB 2.0 hub connected next two USB3 disks, on which in turn an external DVD-Brener, 2 Bluetooth receiver, another external hard drive and - most importantly - a USB sound card to operate. Conclusion: all connected devices function even with simultaneous operation properly and without losses - and that goes for the USB sound adapter! For Laptop therefore only performs a single USB cable, connected to the eight peripheral devices and work perfectly. I separate this one cable I'm mobile, cable and turn the notebook replaces the desktop. The whole course during operation. Therefore, full marks to the unit and the price-performance ratio.
