I can't see my device in Android adb list

I have LG G3 with android 5.0 lollipop and I want to connect it to my laptop with windows 8.1 OS (For using unity remote).

When I connect my phone I can access to storage but I can't see my device in adb.exe . I tried many solution like this and this but nothing work for me.

For now in developer mode I checked these:

• Stay awake

• USB debugging

• Allow mock locations

And I installed the driver from lg website. This is output for adb usb command:

 shell@g3:/ $ adb usb
 adb usb
 error: device not found

Actually I really confused because I think it recognize my device and show g3 name but I don't know why it can't show my device name in attached device!!!

Without lg driver installed, my device in device manager is like image below and when I try to update the driver using Android\android-sdk\extras\google\usb_driver it say: Windows could not find driver software for your device

And when I install lg driver, my device is like image below and again i can't update driver and it say: Windows has determine the driver software for your device is up to date
