The USB 3.0 card has been recognized by Win7 64bit now and is working properly. On the Driver Mini CD are 3 different versions of drivers on it. Fresco 3.0 (FL1000) / NEC / VL800 However, all 3 outdated, as here already reported by some. Also No description at installation and which driver is responsible. It is a VIA chipset on this card. The driver on the CD it is VL800, Version V1.41A WHQL from 20.12.2010 The driver works and the card can be operated with it. However, there is a newer version of VL800 driver. Version V2.10b WHQL (6.1.7600.2108) from 01/31/13 On the VIA website he was, oddly enough, not to be found. On the page "station-drivers.com/page/viachip.htm" he is available for free download offered. Simply enter the address set in quotes on Google, is equal to the first above. Then roll down to the little blue box (USB) Driver Version 2.10b Now you can 2h. Walking ... the download of 66.6 MB with only 7-10 KB / s! Also on some other sites it was not offered faster to download. Copy a 18.8 Gb movie file took with USB 2.0 (12 min. 24 sec. With about 27 MB / s) With USB 3.0 (3 min. 49 sec. With about 88 MB / s) Around 9 min. faster than USB 2.0 Speed differences or otherwise not determine between old and new drivers Apart from the lack of information to the driver CD, I'm happy with the USB 3.0 hub.
