Unable to debug in LG Optimis L7 I am unable to enable debugging mode in LG Optimus L7 Dual. I am connecting the mobile to my PC and choose LG Software mode(read this in a blog that had discussion about LG Optimus). The USB Debugging option in Developer Options is greyed out. Once i unplug it, it glows and I enable it but when I connect and try to debug,my eclipse does not identify the device. Any help will be much appreciated.
As your computer is running Windows, you need to install the appropriate device driver first. Most manufacturers offer one for download on their resp. websites, specifically tailored for the device in question; but that would also mean you'd need multiple drivers if you had multiple devices.

A good solution reported to work fine with multiple different devices, and also supporting Windows 8 fine, is Koushik Dutta's universal adb driver. This would hence free you from the hazzle of possible driver conflicts, if you one day decide to use a different/additional device.
