I just purchased a Koutech HU-430 4-port USB SuperSpeed hub.

When plugged into a USB-3 port using the included USB3 A/B cable, Windows detects it as a "Renesas Electronics USB 2.0 hub".

enter image description here

Does this mean the device is faulty, or I need to install another driver?

The VID is 0x2109, PID is 0x3431 as shown:

Upgrading to the latest Renesas driver (2.1.25.0) fixed the issue.

enter image description here

My motherboard manufacturer hasn't bothered to place the new driver on their website, but Intel has it here

As seen, the hub shows up as two devices (with the correct driver), here are the descriptors for the second device (Unfortunately I didn't notice whether this was listed before the driver upgrade):

External Hub: USB#VID_2109&PID_0810#6&2d180087&0&1#{f18a0e88-c30c-11d0-8815-00a0c906bed8}

Nice detective work on the driver, how did you ever find it? Which Motherboard do you have? –  Moab Oct 10 '11 at 3:39
    
@Moab: I have a Gigabyte GA-P55A-UD4P. I found the driver based on a clue left in a Newegg review saying to get it from Intel, took a little hunting around the Intel download site. –  Ben Voigt Oct 10 '11 at 3:46
