I have a tablet with a cracked screen, but I can use it with usb mouse connected via OTG. One problem is that I cannot connect it in debug mode because whenever I connect my tablet to PC, the message "Allow USB debugging?" appears. So it's a problem: while tablet connected to PC message appears, but in order to accept it I need my mouse connected, but USB port is busy. I have no root, but I have recovery. So is there a way to deal with this message? I know that I can use bluetooth mouse, but I wont have it as soon as I want to debug my apps.
