Hi:

Installing this driver and restarting the PC, should resolve the USB problem...

This package contains the Intel USB 3.0 eXtensible Host Controller Driver for supported notebook models running a supported operating system.

For the Unknown Device, please post the hardware ID for it so I can figure out what driver it needs.

Use this guide for how to find the hardware ID for a device...

Hi,

I installed sp81158.exe as you said and it fixed my problems.

The USB ports now work and the unknown device disappeared from the device manger.

Thank you for your help.
