an USB connection mode on Android devices which allow a USB connected computer to directly interact with the device.
USB debugging is a connection mode on Android devices which allow a USB connected computer to interact with the device. This can be used to e.g.
- transfer data between the computer and the device
- reading log data from the device
- execute commands directly on the device
- debug applications running on the device
More details can be found e.g. in our adb tag-wiki.
By default, USB debugging is disabled with stock ROMs (some custom ROMs however have it enabled by default). To toggle it on or off, you can find the corresponding switch in Settings › Development – a section originally hidden with Android 4.2 and up. You can make this section visible by going to Settings › About device and "hammering" the entry telling your ROM's build version until a toast-message congratulates you for having become a developer.
