    Windows 10 + 7 Dual Boot Problem


    In Windows 10 mouse and keyboard (USB 3.0) works always fine. When i start Windows 7 after i turn off Windows 10 my mouse and keyboard not working anymore after Windows 7 startup. It works if i Disable or Enable EHCI in BIOS. Internet not working if i disable EHCI.

    Did you install the usb 3.0 drivers on windows 7 ?

    Did you install windows 7 using UEFI or Legacy mode ?

    Can you plug the mouse and keyboard into 2.0 ports ? Does the PC have any ?

    Which OS came with the PC ? Which OS did you install yourself ?

    Did you make any changes to the Bios before installing either OS ?

    It's very difficult to us to understand what you have to find a solution to your problem.
    - Edit your profile with all your hardware information.

    Tell us the story of the installation
    - How was Win 7 and Win 10 installed? Different disks, different partition or virtual machine?
    - On Win 7 go to Device Manager and see if there is any missing driver.

    I have two SSD disks. One for Windows 10 and one for Windows 7.

    Only Disable/Enable EHCI multiple times in BIOS helps. Internet works fine if i only use Windows 7. When i'm using Windows 10 and i go to Windows 7 internet not working anymore (No Internet Access). I don't have problems with internet in Windows 10 only in Windows 7.

    On BIOS settings:
    Did you install Win 7 as UEFI or Legacy?
    How are the CSM settings?
    Is Secure boot = Other?

    - On Win 7 go to Device Manager and see if there is any missing driver.
