LG G2 vs980 not recognized by ADB devices command (Win7 on virtualbox)

Question

I have been developing android mobile apps via eclipse in school for some time now, deploying the apps to virtual devices. However, I now want to deploy them to my LG G2 android

Answer 1

When I upgraded my LG g2 from Android 4.4 to 5.0.2, usb debugging stopped working.

I didnt have an "Internet" option for USB connection method.

Through lots of trial, error, searching, experimenting, the I found that enabling "USB tethering" (in Settings -> Tethering & Networks -> USB Tethering) did the trick. Once I enabled USB tethering, I could download debugging programs via adb/AndroidStudio. Before USB tethering enabled, adb could not recognize my 5.0.2 device.
