OTG Power

This software requires the device to be rooted, it works only on Samsung Galaxy S III. This is a simple app allowing user to enable or disable power to USB OTG by executing following shell command with root privileges:

echo "1" >> /sys/kernel/debug/regulator/8226_smbbp_otg/enable

(argument "1" for on, "0" for off). It also allows to execute any other command typed in. Last command executed is saved. When the app is restarted it can be executed without typing it in again.

Device's battery will not charge when power to USB OTG is enabled. Disable power to USB OTG before connecting your phone to PC or a charger. It works with mouses, gamepads and other devices with low power consumption. Not tested on hard drives etc. For devices with higher power consumption a special cable is required (one that allows plugging in charger or power bank).
