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.

My motherboard: ASUS Z87-PRO.

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.

I have no Idea what SLO in your system spec means.
Please us this tutorial by Brink to fill in your system specs.

SLO means Slovenian Language because i'm from Slovenia (Europe).

If i change "Boot from Network Devices" in CSM settings in BIOS internet works in Windows 7 but when i start Windows 10 and go to Windows 7 internet not working in Windows 7. Works again if i change "Boot from Network Devices".
