Windows 7 - USB keyboard and mouse do not work once Windows starts

The following happens to me occasionally:

The keyboard works perfectly in BIOS, at POST and while booting Windows 7/64 Ultimate (I can tell from the [NUM LOCK] LED shining bright). But as soon as the Windows Login screen appears, both, USB mouse and USB keyboard, stop working.

I can tell this from the [NUM LOCK] LED going off and both, mouse and keyboard, not responding.

There is no particular delay discernable. Even waiting for minutes doesn't get the mouse or the keyboard back working. When this happens, the only way to get both, mouse and keyboard, back working is to hard-reset the machine.

I noticed this strange behaviour with several keyboards, mouses and different mainboards. So it doesn't seem to be an issue related to a particular hardware device.

Independant from that I also noticed the following:

  • Currently I'm using a GIGABYTE Z68XP-UD3-iSSD mainboard. If I enable XDR (caching the system disk with the small SSD drive) then Windows 7 boots very quickly but keyboard and mouse get deactivated for approx. 5 seconds when the Login screen pops up.

.

  • When installing Windows, the keyboard rarely didn't enable during POST at all.

I noticed that several people share this same problem. Is this an intrinsic USB HID problem? Or is there some bug in Windows that needs to be fixed?

    Hi,

    This could be a power issue, where Windows is shutting off the power to your USB ports. Try this:

    Open Device Manager

    Click the "Universal Serial Bus" tree

    For each "USB Root Hub" do the following -

    Right click "USB Root Hub"

    Select Properties

    Click Power Management tab

    Make sure the box marked "Allow the computer to turn of this device to save power" is NOT checked.

    Try rebooting now. Hopefully that will take care of the issue.

    How does one do this without a working keyboard and mouse?

    Hi Guys,

     This is an old topic i see but facing with same problem here.. 

    My problem is same as described on post 1

    When the PC turned on in very first secs, everything works fine, so i c an enter the UEFI BIOS or can use some other shortcut keys (preboot acces like F2, F4, F6, F8, F10 and F11) to enter some menu's like windows boot options, BIOS, PC Boot options etc. But just a few sec before the login screen appearing my keyboard and mouse going off. No response and not sign of life. All leds or others lights goes off and PC actinf as if no keyboard or mouse connecte.

    It is vey annoying, tried to safe mode to login but as soon as login screen appears my input devices turns off. Waited like 15 minutes (a few times) after readed posts but not helped me.

    I am using also a SSD HDD from a very known brand and my motherboard is a ASRock Z77 Pro3 and this serie has not this kind of issues.

    Also tried plugging off all usb devices from PC. It works but till i  shut down and turning on the system again. Then my nightmare comes back. 

    I recently installed nothing. No soft or hardware. PC is being used only when we need it like 1x per week for mx. 1 hour.

    Running on Win 7 Ultimate geuine 64bit 8GB DDR RAM and ssd 240GB+SATA 1TB

    See 5th paragraph of original message...

    Yes.

    No, only my current machine uses an SSD system drive. The previous one didn't.
