Another USB Question

A follow up to my earlier post about USB 3 external drive not working properly.  I enabled USB Optimization in BIOS and that seemed to help but USB functionality took longer after windows booted.  So I went back into BIOS and disabled the all fast boot options.  Now when I boot I get a message in the taskbar area that my device will operate faster if plugged into a USB 3 port....which it is.  I am getting this message everytime I boot into Windows.  According to device manager the USB 3 is working fine.  Basically its acting as the USB Optimization is still enabled.  How can I tell whats going on and how do I fix it?  This was not a problem until I enabled the USB Optimization the first time (and its now disabled).

 

Thanks for the help again,

John Marrocco

    Hey John,

    This may not be your problem!

    But there seem to be a problem my Intel Mobo's related to USB 3.0 too.  I have a DZ68BC Mobo and I have no USB 3.0 devices connected to it and I have many Event Viewer ID 56 errors.  These showed up from day one of my build.   I have reported it to Intel today.  You may have the same problems.

     

    In researching this it seems to have something to do with the Renesas Electronics Driver,

     

    The error say... Driver PCI returned an invalid ID for a child device (FFFFFFFFFFFFFFFF00)

    See if you have this software go to Start>Renesas Electronics>USB 3.0 Host Controller Driver>3.0 Host Controller Utility, them right click on properties. Now click on the Security Tab then see if you have some Accounts Unknown followed by a long number in the User/Group window.

    Hope you find your answer soon.

    Thanks for the reply.  The USB controller on the Z77 chipset is Intel so I'm pretty sure it wouldn't be the exact same problem but I'm going to check my event viewer in any case.  I guess I should go ahead and make a report to Intel.
