Last week I upgraded my ASUS Zenfone 5 to Lollipop 5.0, before doing that, I backed up all my files to my pc via USB and it worked just fine. When I want to reconnect my phone, it didn't show anything. There's no notification for verification. USB Debugging is on and I checked the MTP option. My phone isn't showing up on the Windows Device Manager too. I tried 2 different cables and 3 different USB ports and it still didn't work. I've installed the ASUS USB Driver for Zenfone 5 A500CG. Please help me to find a workaround. Any kind of help is appreciated.
