Answer 5

enable USB Tethering. The device would be listed via adb devices (workes for my LG G2/Lollipop)

Answer 6

First check whether the device is attached or not with "adb devices" command (it is inside the platform-tools directory).

Just for information, to start with Android application development with a real device, you have to change some settings:

1. Select the "Unknown sources" checkbox; you find it in "Settings->Applications->Unknown sources."
2. Select the "USB Debugging" checkbox; you find it in "Settings->Applications->Development->USB Debugging."
