USB-charging the Nexus 4 on Windows 7

There is a bug on Windows 7 that prevents the Nexus 4 to charge when it's connected to a USB port. The problem seems to be related to the latest Nexus 4 update in combination with the Windows USB driver. Luckily there is a workaround to this problem: simply disable MTP mounting on the Nexus 4:

• Go to Settings > Storage > Menu > USB Computer Connection  
• Unclick Media Device (MTP) 

The Nexus 4 should now charge when plugged into a Windows 7 computer.

Enable MTP support on Elementary OS

I'm currently running Elemantary OS on a Medion E1210 (Akoya) netbook as ubuntu became too heavy. The netbook has been upgraded with a 128GB SSD from Kingston and is operating very smooth considering the limited cpu. One small problem remains: my Nexus 4 only mounts as a "Media Transfer Protocol' device (MTP) instead of the classical USB Mass Storage device. 

Luckily, it's very easy to add MTP support to Elementary OS by executing the following commands in a shell :

sudo add-apt-repository ppa:langdalepl/gvfs-mtp 
sudo apt-get update 
sudo apt-get upgrade 

After reboot, the nexus 4 was mounted properly.
