The supplied driver CD I had, incidentally, already alone therefore use because there was on the HP of Logilink no drivers to 4x variant.
Respect. Speed can be so properly by start and two USB 3.0 Flash Drives (A-Data), the values were achieved.
With wider USB sticks there could be any problems because the distances between the ports are not overly large. At least the distance to a port is slightly larger. Whether the power connector on the board is generally required, or only for charging USB devices, I have not yet tested. This, incidentally, has no safety bar, so you should carefully possibly go to work.
Total absolute buy recommendation.
Update:
Meanwhile, hanging on the map 2 external USB 3.0 hard drive, a USB 3.0 flash drive and a USB 3.0 2x hub. Everything works just fine. Once the map was suddenly no longer recognized by the system after various installations - I thought it was a failure. Map expanded, refitted and works perfectly.
There are newer VIA WHQL driver, just search for "VIA USB 3.0 Host Controller Driver 6.1.7600.1902 WHQL" googling.
