Do Not Use These Drivers on Windows 8 or 10 as it will break USB3 functionality.

If you've installed your OS from scratch or if Windows 7 has changed the USB3 drivers after an update you'll need to provide drivers for our USB3 card. You will probably need to remove the card in order to see the model number. Below are the drivers for each model:

3U3F-PCIE4XG201 - renesas_usb3_2.1.39.0-200.exe
3U3F-PCIE4XG202 - renesas_usb3_3.0.23.0-202.exe
