Asus Zenfone 2 USB debugging Problem [HELP]

When I Try to connect My Zenfone to PC & also trying to connect on debugging mode then it show display that debugging section is totally disabled & showing message "Device is in Charging mode, USB debugging is disabled.
&
2nd Problem is Media Device Not showing in Mobile & PC Also.
PLZ HELP & GIVE ME PERFECT SOLUTION
I have same problem. After switching over in my car to charging only - my Zenfone is also saying "Device is in Charging mode, USB debugging is disabled" I can't find any switch to take it back. Also the same with Media Device not showing in Mobile & PC.
How to make this working again???
The PC connection mode on your phone is set to "Charge only". Idk about the stock ROM, but on CyanogenMod you just press the notification that shows up when you connect the phone to change the mode

Dear wasiq224,
Thanks for your answer, but is not working. I'm on CyanogenMod - but there is no notification shown up. Phone is quite and also PC - no message.
Even if I press under "STORAGE" -> "USB computer connection" the phone is saying: "USB is now disconnected". I checked already various menues for some settings without result. Google was also not help in this matter.

Try going to Developer Options>Disable USB Debugging, then reboot. Then connect your phone and try going to USB computer connection again, and enable whatever connection mode you want. You can re-enable USB debugging after that.
Dear wasip224
Checked once more the debugging setting's. But if the phone is connected to the computer or not connected, disableing USB Debugging is not possible. This item is greyed out all the time. See attached pictures.
Best regards

How you did do this?? Did you uninstall the driver first? Where I can find this?

I'm at work now, but you use Explorer and go to the folder where you extracted the drivers and use right-click --> properties in one of the files there. There is a tab that lists certificates. Just to be sure you can temporally disable driver signing verification.

This instructions works in windows 8.1 and 10.

Hi all,
Could you install latest Intel USB Driver from this link?
https://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices
Reupdate the driver manually and let me know.

Doesn't work for me, it says it cannot find the files. In my win10 install i have two problems, ADB only works if i disable driver signing verification and MTP doesn't work. I tried running sfc /scannow and it says WinUSB is corrupt and cannot be repaired (probably why MTP does not work). I tried using intel drivers for both and it does not work. Only ASUS works (but fails because of certificate) for ADB Composite Device, but mtp doesn't work anyway.
This tutorial could help you anyway.

Hi Kras and thank for the response!
I Tried it too but in my device manager it wont show any device related to asus nor adb.
Tryied to boot into TWRP but no MTP either.
I Tried USDBview but doesnt show. The strange fact is that the phone charges normally.
It happened after i switched to CHARGE ONLY... after that, could never go back "/
I think i´ll try to revert EVERYTHING to stock. Somethings not right.
Another information, the cellphone charges, i´ve tryied to unistall and reinstall every adb usb_driver but in driver manager, nothing appears, even an exclamation. Tried to force install drivers, nothing either. All this happened after set CHARGE MODE i´m so pissed off and frustrated
This is a shot in the dark, but in device manager you can click View>Show hidden devices.
From there you can truly uninstall all drivers, and then reboot and try reinstalling. Maybe this will help.
Also, different ports, different cables?
If it's just for file transfers have you also tried something like AirDroid or Dropbox/Google Drive/Mega?

help me plzzz..

Are you seeing any adb prompt in your phone when you connect it to the pc? If not then the phone mat not be properly connected. If possible try using a different USB cable.

Noi there is no promt on ..phone
Disconnect the phone from PC then go to developer options and choose revoke USB debugging permissions. Then connect the phone again and run the adb devices command. You should see a prompt in you phone to allow USB debugging. Select trust this computer and cos ok. ADB should work after that.
