    Intel 8 series/C220 series USB 3.0 xHCI driver - Can I force a device to be USB2.0???

    Jonelli

      I have a special USB audio interface that does not communicate to its software in Win7 using USB3 drivers.  Disabling USB3 altogether works fine with it, but I prefer not to do that.

      When USB3 is enabled, the device always shows up under the xHCI driver instead of the EHCI driver.  Is there some way to force it to only use the EHCI driver in Windows????

       

      Thank you!!!

      Attached is a photo of Device Manager how it shows up with USB3 enabled.  If there was some  way to tell Windows that this device is USB2 only?
