Ultrabook USB 3.0 Port problems

I have an Asus UX-31 Ultrabook, to extend the USB 3.0 port from one to three I bought a "Logitech Giga 3 port hub -USB 3.0 Ethernet adapter" and upon installing the drivers, the USB 3.0 port stopped working completely - for all devices.On the device manager the now non-functioning root hub driver information stated
Fresco Logic xHCI (USB3) Root HubDevice Status: "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"Hardware ID: FLUSB\ROOT_HUB_FL30Driver Version: 3.5.93.0
I unsuccessfully tried many things to get it working, system restores (which got the port working but not with the new external hub) and updating the drivers (in hindsight -not the latest ones).
The Ethernet hub utilizes the
AX88179 -- USB3.0 to 10/100/1000M Gigabit Ethernet Controller
which is more than the older USB 3 root hub driver can handle
The Asus website is useless, it does not have the most recent updates for the USB 3 drivers
so I went here -
http://drivers.softpedia.com/get/Other-DRIVERS-TOOLS/Fresco-Logic/Fresco-Logic-USB-30-Driver-351000.shtml downloaded this which is version 3.5.100.0 and this driver can handle the Gigabit ehternet controller, once installed the USB 3.0 port became functioning again and the AX88179 ethernet hub drivers which had already been installed were working fine.

Windows 7 drivers and Epson Scanners

Some more useful info to disseminate into interweb.......

Many older Epson scanners and their drivers don't work in Windows 7 and its 64bit architecture.

Epson are useless at getting all their products up to speed, only the newer, more popular models are currently supported.

My scanner the GT-8200UF was not supported by Epson. I found a easy workaround. Vuescan - a scanning software which is the software I use anyway as it's excellent scanning software, far superior to any of the junk that most manufacturers bundle with their products.

Vuescan made by Hamrick, can use its own drivers to enable your scanner to work.

..and it works perfectly, thank you Hamrick and Vuescan.
