Try to uninstall all drivers then replug the phone, and check if detected, sometime old drivers from other devices may cause problem. If still not working try to reinstall generic windows adb drivers.
it wasnt drivers problem, accidentally i unchecked both MTP and PTP options.
So when i repluged usb cable, notification "connected as a media device" disappeared and never showed up again...
Solution: Settings>Storage, push menu button and click USB computer connection
