    USB 3.0 Keyboard Lock light issues


      I've been having an issue lately with my keyboard and I think I have narrowed down the cause to Intel's USB 3.0 drivers.


      When my keyboard (Corsair K70) is plugged into any USB 3.0 port on my computer (ports are through Z370 chipset), after a short period of time or nearly instant, my num, caps, and scroll lock indicator lights on my keyboard freeze when using those 3 keys. The only way to unfreeze them is by unplugging/plugging back in the keyboard. This issue does not happen on my ASMedia 3.1 ports.


      I have seen numerous other forum posts online discussing this issue with many different keyboards and motherboards. I have gotten a replacement keyboard, updated all my drivers, and even reformatted my computer and the issue will not go away.


      Info about my PC that may help:

      -Gigabyte AORUS Gaming 7 Z370 Motherboard

      -Intel 8700k

      -Corsair K70 keyboard on latest drivers/firmware


      Drivers installed:

      Standard USB 3.0 eXtensible Host Controller - 1.0 (Microsoft) -- Version 10.0.16299.125

      USB Root Hub (USB 3.0) -- Version 10.0.16299.64

      Generic USB Hub -- Version 10.0.16299.64

      USB Composite Device -- Version 10.0.16299.15


      Edit: I found some signed drivers that I was able to install on Windows 10 and still received the same issue.


      Driver was '64bit Intel USB 3.0/3.1 Drivers v5.0.4.43'.

          Hello, akrios.

          Thank you very much for contacting the Intel® Communities Team.

          I understand that you are facing some issues with your USB 3.0 drivers.

          Allow me to explain to you that Intel® does not provide drivers directly for your motherboard. Indeed, we do create the chipset that your mainboard uses nonetheless, the manufacturer of the board may change its specifications as its convenience. I would highly recommend you to verify with GIGABYTE® Support to double check if there are any USB drivers available for your system. 

          Antony S.

            Thanks for the response. I've spent the past few months really trying to pin point the cause of this issue. Everything from the keyboard itself, keyboard drivers, Windows, Intel drivers, etc. Thanks for pointing me in the right direction I'll check with Gigabyte.
