I upgraded to the window 10 tech preview from windows 7 and now my mouse and keyboard dont work once the os loads up and brings me to the sign in screen. I cant even roll back to windows 7 now because I have no mouse input except for when the bios splash screen is showing. Any help would be amazing thank you.

    Have you tried to put your keyboard or mouse to other usb-ports? Mine didn't work in the usb3.0 ports (usually blue color) but started to respond after i switched them to usb2.0 ports (black ports)

    Yes.  I moved them from Black to Blue to Red, rebooting for each.  No luck.

    Are other USB devices working on this system (ie, is it just keyboard/mice that are not working)?

    Are other USB devices working on this system (ie, is it just keyboard/mice that are not working)?

    Before the first reboot, I was able to access my USB media bay and look at files on a USB drive and SD cards.  After the first reboot once in windows 10, I cannot get past the login screen.  I did plugin different model USB keyboards and USB mice, but they are just in a hung state.  I noticed the keyboards maintain the LED light state from which they were booted, but after Windows 10 comes back up, I can't even turn the NumLock or CapsLock lights on or off.

    Is there another method I could use to test the USB functionality at the login screen?

    Thank you.
