Nexus 4 problems connecting usb mtp I recently bought a Nexus 4 and I encountered a real issue with my computer (Windows 8 Pro 64 Bit) not being able to connect in USB mode. It does however work with Camera PTP mode, which I find very strange.

I have tried/tested with:


Different usb cables
My computer with the same OS of Windows 8 64 bit isn't connecting compared to another computer with the same OS.
Removing its current drivers on my computer and reinstalling drivers from Nexus 4 ToolKit
Restarting the computer
With/without USB debugging mode


Note that the device is visible on the computer although it's not recognized:
I have Windows 8.1 and I had the same problem, PTP working, MTP not. I was following the steps suggested in this page but it wasn't doing the job, until I made some previous steps, and slightly changed the last part. Summarising what I did is:


Connect your device.
Unistall ALL the drivers from the Device Manager, be sure to go in "View"->"Show hidden devices" and then check that all of the following are unistalled:

a) Android Devices

b) Other devices

c) Portable interfaces
Now disconnect your device.
Check the PTP mode and connect your device. Wait for the drivers to be installed.
Without disconnecting check the MTP mode on your device and wait the drivers to be installed again.


Now it should WORK!! At least it did it for me ;)
