    Problem: USB 3.0 Extensible Host Controller & USB 3.0 Gigabit Ethernet adapter

    5816347092

      Whenever I plug in my USB 3.0 Gigabit Ethernet adapter, iusb3mon.exe uses 25% CPU.  It will continue to use 25% CPU even after I remove the Ethernet adapter.  Has anyone else encountered this issue?  Is there a compatilibity issue between the Intel USB 3.0 Extensible Host Controller software and USB 3.0 Ethernet adapters?

       

      As of this post, I have all the latest drivers installed.  I've tried a clean install of the OS, software and updates, but the issue remains.  USB 3.0 flash drives do not cause iusb3mon.exe to use any CPU.

       

      Hardware / software:

       

      Asus Zenbook UX32VD-DH71

      Windows 7 Ultimate x64 SP1

      Intel USB 3.0 eXtensible Host Controller Driver (version 1.0.7.248)

      Startech USB 3.0 Gigabit Ethernet adapter (USB31000S)

      ASIX AX88179_AX88178A Windows 7 Drivers (version 2.0.0.0)
