C216 USB Enhanced Host Controller updates?

I use DriverDoc, and it tells me that my "Interl(R) 7 Series/C216 Chipset Family USB Enhanced Host Controller - 1E26 and 1E2D" is out of date. My current version is Intel 9.3.0.1011, but DriverDoc shows that the new version is 9.3.0.1028. Where may I download Version 9.3.0.1028? Thank you.

P.S. My computer (OS is Windows 7) is encountering Usbser.sys crashes, so I am trying to update the drivers.
