The controller card has a NEC / Renesas chipset is processed properly and also came with me to salvation. The driver CD would however like other reviewers certainly can also be broken, because the content does not help anyone further - outdated drivers, eg for Win 7 Pro 64bit unsuitable. On the online bill (!!), a link is to an FTP server of the sender, where you can download a fairly new driver - but by far not the most current. With this driver the card works temporarily, but is sometimes more when connecting external USB 3.0 hard drives (different hard drive manufacturers!) Asked for formatting (at existing data!), Here only helps repeatedly plugging and unplugging the USB cable. Ridiculous, then provide drivers on CD rather just cheaper, saving the CD and link a current driver: Conclusion.
Thus, the card works fine, I did the following (Win 7 Pro 64bit): 1. Firmware update the chipset to version 2020 (my card has the chipset D720201 & uPD720202). 2. Restart. 3. Download a relatively current driver (eg, version 3.0.23.0) and installation. 4. nor installed with the driver package utility program under START Finally - All Programs - Renesas Electronics - USB 3.0 Host Controller Driver - call USB 3.0 Host Controller UTILITY and there the box "Disable the USB 3.0 power management functions" set. DONE!
