Update your computer's drivers using DriverMax, the free driver update tool - USB Universal Serial Bus - Intel - Standard Universal PCI to USB Host Controller Computer Driver Updates. Apr 25, 2012  I also notice in the Device Manager in Other devices -> Universal Serial Bus (USB) Controller -> The drivers for this device are not installed. (Code 28) To find a driver for this device, click Update Driver. The device manager. ALL ANNOUCEMENTS ACCOUNT. Maximus V Gene Z77 USB Trouble, Mouse Freezing.

I appreciate the suggestions, but I have done those things, several times over, with no help from either.

Using the Troubleshooter (have run it several times with the same results), I get the details:

Hardware changes might not have been detected
Scan for recent hardware changes

I get the exact same results every time with the 'Fixed' and then 'Completed' reports, but nothing changes and I still cannot get USB3 performance from my USB3 ports.

I have also tried the 'Update Driver Software' several times, and each time I get the message that 'The best driver software for your device is already installed'. So no help there at all. Still no USB3 capability.

I also tried the 'Update Driver Software' by removing the driver altogether so that Windows has to find a 'new' driver, but Windows just installs the very same driver that it was before. I also made sure to allow Windows to search online rather than on just my local drive, and it still installs the same driver as it originally was with no change in USB3 behavior.

I'll note again that USB3 worked great with my Win7Pro operating system, and I only lost USB3 the moment I upgraded to Win10.

I am not a tech, but the only difference from the time I lost USB3 capability was the Win10 upgrade, so there seems to be some kind of compatibility problem with my (long used) USB3 driver and the new Win10 operating system.
