Thank you for joining the Intel® community. My apologies for the inconvenience.
At this stage the proper driver for your computer model should be provided by your computer manufacturer. I searched for your computer model and found the following driver: Intel USB 3.0 Driver for Windows 7 (32-bit, 64-bit) - Lenovo G400, G500
I would (re-)install the latest release of the Intel Chipset software package as well.
