Wirebug

Allows you to enable or disable debugging over Wi-Fi from within the device, without a USB cable. This can come in handy if your USB cable broke or you lost/forgot it somewhere.

Note: Requires root permissions.

Why does it need root?

Wirebug needs root permissions to write to the system.adb.tcp.port property and to restart the ADB daemon.

If the su command is not available it will only be able to reflect the current debugging status in the notification area but not change it (may be still be useful in case you use adb tcpip).
