How to Enable USB Debugging for LG Optimus (LGD415). Android version 4.4.2 (KitKat)
Go to this website and download the drivers to your phone:
http://www.lg.com/us/support/mobile-support
For example, mine would be:
http://www.lg.com/us/support-mobile/lg-LGD415RD. Then click on “Software Update & Drivers”

On your phone, you need to enable USB debugging. To do so,
Go to “Settings”.
Go to “About Phone”
Go to “Software Information”
Tap “Build number” five times.
A pop-up will appear saying “You are now a developer”. Your’re not done yet.

Go back to your phone’s home page by pushing the home button.
Go to “Settings”.
Go to “Developer options”
Click the “USB debugging- Turn on debug mode when USB is connected”. A blue checkmark will appear.

(EDIT: If USB Debugging is greyed out, unplug your phone. USB Debugging should no longer be greyed out. If it is not greyed out, check the box and plug your phone into your PC.)

Unplug your phone from your PC. Then plug it back in. On the pop-up, make sure you set it to “Media Sync (MTP)”.

Now your phone will show up on an option when you want to run your app in Eclipse.

(Look for dialog box on phone and agree to allow debugging connection with your computer.)

(Also, go to Control Panel | Device Manager and make sure there are TWO entries for your phone, similar to those expanded below.)

I had an LG Android phone  and could not get USB to work with Windows  even after trying the following     Settings   About phone   Software info Tap  Build number  7x  and Activate Developer mode Settings   Developer options   USB debugging  ON  Settings   Developer options   Select USB Configuration   MTP Plug into Windows PC with USB cable     It DOES show the phone as charging via USB  so the plug must be OK   but it does not show up under  This PC  in Windows File Explorer as a Device Drive   grrr    Turns out that not all USB cables are the same     some USB cable manufacturers only make their cable with 2wires instead of 4wires  so that they will charge  but not pass data through the cable     so if software solutions do not appear to be working  try changing the USB cable        im writing this here so that maybe someone else doesnt have to waste half an hour figuring out that some USB cable manufacturer doesnt include all 4 wires in their USB cables    grrr

I have a feeling that if you have a corporate phone  your corporation IT might also be blocking USB Debugging   I ve tried all the different connection modes and the USB Debugging option remains firmly greyed out   I m trying to get in to enable the BATTERY STATS for GSam Monitor Pro  but I think it s disable through the Airwatch MDM software my company makes me use   They pay for it so I guess I m stuck

After countless attempts  I found the following quote      If you are using My KNOX  you cannot enable USB debugging mode while the container is installed  Unfortunately  you have to root your device       - continue reading   Furthermore make sure    your USB-cable works your connection type is MTP  or PTP in some cases  to enable USB debugging before pluging your device via USB-cable   I switched to another device without KNOX  not rooted as well  to save time  Maybe this quote will save someone some time  It was the only explanation to me in this case   Cheers

Just ran into this on the LG Rebel LTE  LGL44VL   As other answers note  you need to change the USB connection mode to PTP  But my phone s control panels were different from stock Android and didn t have such an option   The option was hiding in a notification that appeared when I plugged the phone in  I had to open the notification tray and tap a notification labeled     Media Device  MTP    Tap here for more USB options

Connect the phone to a PC  make sure your developer options are enabled  Then  connection type must be MTP or File Transfer  Charge only does not allow USB debugging disables the option
