thank you for very good product
This Expansion Card actually did what I had wanted it to do. I had an issue with USB 3 ports. After resuming from sleep my Win10 PC (Z77 chipset) didn't "wake up" USB 3 ports. My PC used to go to sleep with some USB 3 ports and USB Superspeed hubs but woke up with only USB 2 ports and no superspeed USB hubs. I found out today that the USB 3 superspeed hub on this card can wake up correctly. In general this card looks solid. Good PCB and good-looking capacitors. Recommended.
