Hello! Old tablet Allwinner A13 good connected to the arduino and new EMATIC EGS005 sees it but not connected. What to do?

I did it! With plugged arduino i run program "USB Host Diagnostics v1.3" and press "start diagnostics" and "yes" in popups dialogs. After this i did reboot. And all. Thank developers this program!
